Where should warning triangles be placed on a two-way divided highway?

The recommended placement of warning triangles on a two-way divided highway is 100 feet in front of the vehicle and 10 feet and 100 feet behind the vehicle. This setup helps ensure that drivers approaching from both directions are adequately warned of the presence of a disabled vehicle.

Placing a triangle 100 feet in front alerts oncoming traffic while the two lower distances behind the vehicle—one at 10 feet and another at 100 feet—help provide a clear signal to drivers from behind. The close triangle at 10 feet allows for immediate awareness while the further triangle at 100 feet gives an additional warning well in advance for safe spacing.

This arrangement adheres to federal guidelines aimed at increasing visibility and minimizing the risk of accidents, especially on the high-speed environment typically found on divided highways. Effective use of warning devices is crucial to road safety and is a core element in maintaining a safe working environment for all road users.
