Intersection Safety FactsStreet Signs

  • About 87% of all collisions are caused by driver error, which includes attitude and behaviour.
  • In Alberta, the most common driver errors resulting in fatal/injury collisions were intersection related: making a left turn across the path of an on-coming vehicle, committing a stop sign violation, disobeying a traffic signal (Alberta Transportation).
  • In Grande Prairie in 2016, 89% of collisions occurred at intersections. The highest risk intersections in the City in ranked order are:
     100 Avenue and 116 Street
     84 Avenue and 108 Street
     116 Avenue and 100 Street
     124 Avenue and 100 Street
     132 Avenue and 100 Street

Safety Tips for Drivers

  • Before entering a main street from a road, service road, alley, driveway, or parking lot, a vehicle must stop unless marked otherwise.
  • Keep intersections clear so that other traffic may proceed if the light changes.
  • When vehicles arrive at a four way stop sign, allow the vehicle that arrived first to proceed first. If vehicles arrive simultaneously, right of way is given to the vehicle on the right, while left turning vehicles yield to approaching traffic. Just because one has the right of way does not mean it is safe to proceed through the intersection. Keep watching for pedestrians and oncoming traffic.
  • Distracted driving continues to play a significant part in the number of collisions at intersections.


  • Fines related to intersection safety range from $155 to $388
  • Failure to stop at a stop sign or red light may result in a $388 fine and three demerits
  • Failure to yield to a pedestrian in a crosswalk (marked or unmarked) carries a fine of up to $776 and four demerits

Frequently Asked Questions

What is the safest way to execute a left turn?

Enter the intersection; keep the vehicle’s wheels straight so that you do not cross in front of oncoming traffic if struck from behind. When there is a suitable space, make sure the turning path is clear of traffic, including pedestrians, and it is safe to go before proceeding through the turn. Be sure to stay on the right side of the centre line through the turn. Only one car should be in the intersection to complete a left turn.

How do I properly turn right at a red light?

Make sure a traffic control device does not prohibit a right turn. If permitted, then you must signal, come to a complete stop, and then turn when it is safe to do so. The only exception to this is when there are free flow turning lanes allowing free flow of traffic turning right.

What do I do in an uncontrolled intersection?

An uncontrolled intersection is any intersection that does not have traffic signs or signals. When approaching an uncontrolled intersection, check left and right for traffic, slow down and be prepared to stop. Yield the right of way to the vehicle on the right. Be alert as other drivers may not be expecting any traffic at the intersection and that could result in a collision.

What do I do if an emergency vehicle approaches a red light with lights and sirens engaged?

Stop and give the right of way to emergency vehicles until they have passed through the intersection. Failure to do so could result in a $233 fine plus three demerits.

What do I do at a T intersection?

At uncontrolled and three-way intersections, drivers must always yield to the vehicle on the right.

What do flashing red and amber lights mean at an intersection?

A flashing red light acts as a stop sign; vehicles must come to a stop before crossing the stop line or crosswalk. Vehicles facing a flashing amber light may proceed with caution after yielding to pedestrians and traffic in the intersection.
