Right Angle Crashes

Right angle crashes involve vehicles traveling on perpendicular streets when one driver fails to yield the right of way to the other.

65% of Right Angle crashes in Fort Collins occur at unsignalized intersections. The majority occur after a driver stops at a STOP sign but then proceeds when it is unsafe to do so.

Common Causes of Right Angle Crashes


Limited Sight Distance

Tip for Motorists:

  • Pull slowly forward far enough to see past sight obstructions. Don’t assume it is clear. Watch for pedestrians and bicyclists in crosswalks before pulling forward.

Running a Red Light

Red light running at signalized intersections accounts for 28% of right angle crashes in Fort Collins.

Tip for Motorists:

  • Anticipate the end of a green light. Let off the accelerator and prepare to stop.
  • Rain and snow increase stopping distances. Adjust your speed accordingly when approaching traffic signals.
  • If you are stopped at a red light waiting, when the light turns green look left and right for red light runners before proceeding.
  • Entering the intersection just as the red light starts or “pushing the yellow” light has serious safety implications. It is always unsafe to enter an intersection on a red light - even just a second or two after it turns red. See the Approach Turn Crash page for a discussion of this issue.

Tips for Motorists:
  • Don’t assume the through lanes are clear if your view is blocked by a right turning vehicle. Wait for the right turning driver to make their turn to ensure adequate visibility
