Two vehicles arrive at a four-way stop at exactly the same time, on roads that cross each other perpendicularly. Which vehicle goes first?

When two drivers meet simultaneously at an uncontrolled intersection or four-way stop, the driver on the left must yield to the driver on the right. This rule applies consistently across Ontario intersections without traffic lights or flashing signals.

You approach an uncontrolled intersection. Another driver reaches it from your right at the same time. What should you do?

At an uncontrolled intersection the driver on the right has the right of way. This rule prevents gridlock when two drivers arrive simultaneously. If the other driver clearly arrived first, they have right of way regardless of position.

You are pulling out of a private driveway onto a public road. What must you do?

Drivers entering a public road from private property have no right of way — vehicles on the road and pedestrians on sidewalks come first. This rule reflects a common crash scenario: a car pulling out without checking for bikes, cars, or pedestrians.

When entering a roundabout, which vehicles have the right of way?

The 'yield to the left' principle: drivers entering a roundabout must yield to traffic already in it. This keeps the roundabout flowing and prevents stops that back up onto the approach road.

At a yield sign where you are about to merge onto a road, you must:

A yield sign creates a conditional stop — proceed only after giving the right-of-way to traffic already on the intersecting road. A full stop is only required when necessary to let that traffic pass. This is the key difference from a stop sign.

At a four-way stop, vehicle A reaches the stop line one second before vehicle B. Who has the right of way?

At a four-way stop, the first vehicle to arrive goes first. The right-side rule breaks ties when two arrive simultaneously. Clear eye contact and patience prevent the uncertainty that causes fender-benders at crowded 4-way stops.

You are driving behind a school bus on a two-lane road. The bus stops and turns on its red flashing lights and extends its stop arm. You must:

You must stop at least 20 metres behind a stopped school bus with flashing red lights and extended stop arm. Passing a stopped school bus is a serious offence with a $400–$2,000 fine and 6 demerit points on a first conviction.

You are driving toward a school bus that is stopped on the opposite side of a two-lane road with its red lights flashing and stop arm out. You must:

On an undivided road, drivers approaching a stopped school bus from either direction must stop. The only exception is if the road has a median or dividing barrier — traffic moving in the opposite direction on a divided road does not need to stop.

An ambulance with flashing red lights and siren approaches your vehicle from behind. You must:

By law you must yield to any emergency vehicle (ambulance, fire, police) with lights or sirens active. Pull to the right, come to a stop, and wait until it has passed. Each second matters in medical emergencies — blocking an emergency vehicle can cost lives.

At a marked crosswalk with no traffic lights, a pedestrian is crossing. You are approaching in a vehicle. You must:

At any marked crosswalk or pedestrian crossover, pedestrians have right-of-way. You must stop and wait until they have completely crossed. Pedestrian fatalities in Ontario are disproportionately caused by drivers rolling through crossings instead of stopping.

What must you do when you approach a stop sign at an intersection?

A stop sign requires a complete stop at the stop line, crosswalk or intersection edge—never a rolling stop. You may proceed only when the intersection and approaching traffic are clear. This rule protects you and cross-traffic from collisions at controlled entries.

A red octagonal (8-sided) sign at an intersection tells the driver to:

The octagonal (eight-sided) red sign is uniquely reserved for the stop command in Ontario and across North America. Its distinct shape lets you recognize it even from behind or in poor visibility. Coming to a full stop prevents collisions and obeys a regulatory obligation.

You approach a stop sign in a residential area. There is no painted stop line and no marked crosswalk at the corner. Where should you bring your vehicle to a complete stop?

When no stop line or crosswalk is marked, stop close enough to the intersection to see approaching traffic from both sides, but not so far forward that you block cross traffic. Stopping too far back leaves you blind to oncoming vehicles; stopping inside the intersection endangers everyone.

What does a red and white triangular yield sign require you to do?

A yield sign is the second-strongest regulatory instruction after a stop sign: give way to cross or merging traffic, and stop only if needed to do so safely. This prevents collisions while keeping traffic flowing when conditions allow safe entry.

How does a yield sign differ from a stop sign in its legal requirement?

Understanding the difference is critical: at a stop sign you must always come to a complete stop; at a yield sign you stop only when needed to give way. Treating yield as 'proceed freely' or stop as 'rolling stop' invites collisions, both of which are Highway Traffic Act offences.

Which shape and colour combination identifies a yield sign in Ontario?

The downward-pointing triangle with a red border is reserved exclusively for yielding — its shape makes it recognizable at a distance and in poor visibility. Each regulatory-sign family has a distinct shape (octagon = stop, triangle = yield, circle = railway) so drivers can respond even before reading any text.

You are on a merge ramp approaching a highway. A yield sign is posted at the end of the ramp. Highway traffic is heavy and closely spaced. What should you do?

Heavy traffic with no gap means 'necessary to stop.' Wait at the end of the ramp until an adequate gap opens, then accelerate and merge smoothly. Rushing into traffic that has the right of way is a top cause of high-speed collisions on Ontario freeways.

A rectangular white sign showing 'MAXIMUM 60' tells the driver that:

Rectangular white 'MAXIMUM' signs set the legal upper limit on that road. Exceeding it is a speeding offence with demerit points and a fine; lesser speeds are permitted when conditions (weather, traffic) require. This keeps speeds matched to road design.

You are driving in a small Ontario town and see no posted speed-limit signs. What is the maximum legal speed you can drive?

Ontario's default unposted maximum is 50 km/h inside cities, towns and villages. Higher speeds in built-up areas are dangerous to pedestrians and children: a pedestrian struck at 50 km/h has roughly 10× the fatality risk of one struck at 30 km/h.

Outside Ontario cities, towns and villages where no speed-limit sign is posted, what is the maximum legal speed?

The rural (unposted, outside built-up areas) default is 80 km/h. On rural two-lane highways this balances travel efficiency against stopping distance, wildlife hazards, and the limited sightlines typical of non-freeway country roads.

How far must a parked vehicle be from an intersection that has no traffic lights?

9 metres minimum keeps sightlines clear for drivers making turns at the intersection. Parking too close to the corner hides pedestrians and cross traffic, a major cause of intersection collisions.

How far must a parked vehicle be from an intersection controlled by traffic lights?

15 metres from a signalled intersection keeps cars out of the signal-visibility zone and preserves room for turning traffic. This is stricter than the 9 metre rule for uncontrolled intersections because signalled intersections have heavier traffic.

When parking facing uphill beside a curb, you should turn your front wheels:

Turning wheels to the left (away from the curb) means that if the parking brake fails, the rear wheels roll against the curb and block the vehicle from rolling into traffic. This is the opposite of downhill parking.

When parking facing downhill beside a curb, you should turn your front wheels:

Downhill with a curb: wheels toward the curb so, if the brake slips, the car rolls into the curb instead of into the roadway. Combined with parking brake and low gear (or Park), this is redundant safety.

When parking facing uphill on a road with no curb, you should turn your front wheels:

No curb means no physical stop — turning wheels to the right (toward the road shoulder or ditch) ensures that any rollback pulls the vehicle off the travelled portion of the road, not into it.

It is illegal to park within what distance of a fire hydrant in Ontario?

Three metres of clear space lets fire crews connect a hose to the hydrant without delay. The other distance values belong to other parking rules (6 m crosswalk, 9 m uncontrolled intersection, 15 m signalled intersection) — do not confuse them.

Parking in front of a private driveway is:

Blocking a driveway traps the resident's vehicle in or out. Ontario prohibits it outright — flashers and time of day do not change the rule. Tickets and tow-away are common enforcement responses.

Parking on the sidewalk is:

Sidewalks are for pedestrians — especially those using wheelchairs, walkers, strollers. Any obstruction forces them into the roadway. Ontario prohibits sidewalk parking at all times; enforcement is aggressive in urban areas.

Parking on or within 100 metres of a bridge or tunnel in Ontario is:

Bridges and tunnels have limited escape routes and reduced visibility. A stopped vehicle narrows an already restricted space and creates high-severity collision risk. The rule is absolute, not time- or traffic-gated.

When entering an angle-parking space, you should:

Angle parking is efficient but hides pedestrians and cyclists behind adjacent vehicles. Signal intent, slow for blind-spot checks, and enter under control so you can stop instantly if someone steps out.

You are driving on a rural highway when thick fog reduces your visibility to almost zero. The safest action is:

In dense fog the handbook directs drivers to pull off into a safe parking area and wait. High beams scatter off water droplets and reduce visibility; stopping in the travel lane invites rear-end collisions; tailing another vehicle means you inherit their mistakes plus a collision risk when they brake.

Your vehicle begins to hydroplane on a flooded road. You should:

When tires ride on water, steering and braking have no effect. Easing off the accelerator lets the tires slow naturally and make contact with the pavement again. Hard braking, acceleration, or sharp steering during hydroplane invariably leads to a skid or spin-out.

Your brakes fail as you approach a red light. After pumping the pedal with no result, you should:

Pump first — some hydraulic systems recover. If not, the parking brake (with release button pressed to avoid locking the rear wheels) plus engine braking via a lower gear is the controlled way to stop. Shutting off the ignition disables power steering and can lock the steering column.

If your accelerator sticks and the engine races while you are driving, your first action should be:

Shifting to neutral disconnects the engine from the drive wheels immediately, letting you brake normally. Only after you are safely stopped off the road should you turn the ignition off (doing it at speed may lock the steering column).

You see a deer standing at the edge of a rural highway ahead of you. You should:

Deer and other large animals move unpredictably — they often bolt toward or across a vehicle. Slowing down preserves your ability to stop. Swerving into the oncoming lane risks a head-on collision that is usually worse than striking the animal.

When you brake hard in a vehicle equipped with anti-lock brakes (ABS), you feel the pedal vibrating. You should:

ABS pulsation is the system rapidly modulating brake pressure to prevent wheel lockup — that is exactly its purpose. Pumping manually disables ABS benefit. Firm, steady pressure lets ABS give you maximum stopping power while preserving steering control.

You notice smoke coming from under your hood. You should:

Any engine smoke or flame is an emergency. Get off the road, kill the fuel supply by shutting off the engine, evacuate to a safe distance (fuel tank explosion risk), and call 911. Opening the hood feeds oxygen to a fire and can cause a flare-up.

Your windshield wipers suddenly stop working during heavy rain. You should:

Without working wipers in rain, visibility collapses instantly. The handbook directs you to pull off the road as soon as you can safely do so — you cannot drive safely without forward vision, and attempts to keep going make a collision likely.

Your headlights suddenly fail while you are driving at night. You should:

Cycle the switch — loose contacts sometimes restore function. If not, any available lights (parking lights, flashers, turn signals held on) provide minimum forward illumination while you pull off the road safely. Driving unlit at night is both illegal and extremely dangerous.

You are involved in a minor collision with no injuries. Your first actions should be:

Stop, engine off (fire risk), hazards on, move to the side (if drivable and safe) to clear the travelled portion. Leaving the scene is a serious offence; refusing to act is not an option; arguing wastes time and escalates conflict.
