Who's Actually at Fault at an Intersection? An Ontario Driver's Guide

Intersections look simple. There are signals, lanes, and road markings telling everyone exactly what to do. Yet some of the most serious car accidents in Ontario happen right at these junctions — and fault is almost never as obvious as people assume.

At Raja Law, we represent injured drivers, pedestrians, and cyclists across Ontario. Time and again, we see clients who believed fault was clear-cut, only to discover the legal picture was far more complicated. Here's what every driver should know.

Left Turns: Having the Right of Way Isn't Enough

Everyone knows that a vehicle turning left must yield to oncoming traffic. What most drivers don't realize is that the oncoming driver can still be found partly at fault — even when they had the right of way.

Ontario uses a contributory negligence framework. That means fault can be divided between both parties. Here's when a straight-through driver can end up sharing liability:

Speed

·       Going 1–5 km/h over the limit usually won't move the needle

·       Going 10+ km/h over often will

·       Modern vehicles record speed, braking, and acceleration data in the airbag control module — what's commonly called the "black box"

Traffic cameras and accident reconstruction engineers can use this data to determine whether speed was a factor. If you were going too fast, your compensation can be reduced — even if the other driver turned in front of you.

Yellow Lights

If a left-turning vehicle was already mid-intersection when the light turned yellow, and you accelerated instead of slowing down, fault may be shared. Courts look at:

·       Where each driver was when the signal changed

·       Whether the straight driver sped up to "beat the red"

·       Whether the left-turning driver was already committed to the turn

How You Position Your Wheels Matters

When waiting to turn left, pull into the intersection — but keep your wheels pointing straight. Don't pre-angle your tires toward the turn while stopped. If you're rear-ended with your wheels already turned, your car gets pushed directly into oncoming lanes. This causes some of the most catastrophic injuries we see.

Right Turns: Where Pedestrians and Cyclists Get Hurt

Right-turn accidents are common. They're also among the deadliest — because the victims are usually on foot or on a bike, with no protection and little room to react.

The mistake is almost always the same: drivers check for other cars and forget to look for people.

Before completing any right turn, your last look must be the crosswalk. Pedestrians crossing legally with the signal, cyclists riding straight through, and other vulnerable road users can enter the crosswalk in the seconds your eyes are on traffic to the left. A split-second lapse at the wrong moment changes lives permanently.

Who Bears Fault in These Accidents?

When a driver strikes a pedestrian in a marked crosswalk, liability almost entirely falls on the driver. A pedestrian crossing on a legal signal will almost never be found contributorily negligent.

Cyclist cases can be slightly more complicated — if a cyclist was riding on a sidewalk or otherwise improperly, some portion of fault might be attributed to them. But even then, it's typically minor. The driver still carries the bulk of responsibility, and these collisions regularly result in permanent, life-altering injuries.

Distracted Driving Amplifies Everything

Whether you're turning left, turning right, or going straight — picking up your phone at an intersection multiplies the risk of a collision and guarantees a worse legal outcome if one occurs. Intersections are exactly where your full attention is needed most. Put the phone down before you get there.

What to Do Right After an Intersection Accident

The actions you take in the hours and days after a collision can significantly affect your claim:

1.     Get medical attention immediately — symptoms sometimes appear hours or days later

2.     Photograph the scene — the intersection, road markings, signal positions, and vehicle damage

3.     Get witness information — names and contact numbers before people leave

4.     Preserve your vehicle data and dash-cam footage — it can be overwritten or lost quickly

5.     Don't concede fault at the scene — the legal analysis is often more nuanced than the moment suggests

6.     Contact a lawyer early — black box data, signal timing records, and traffic camera footage don't stay available forever
