What is the recommended action if you encounter a vehicle that has stopped in a low visibility area?

When you encounter a vehicle that has stopped in a low visibility area, using reflective triangles to alert other motorists is the recommended action because it enhances safety for both the stopped vehicle and other drivers. Placing reflective triangles provides a visual warning that helps alert approaching drivers to the presence of the stationary vehicle, reducing the risk of accidents. The triangles should be placed at appropriate distances behind the vehicle to give adequate notice to oncoming traffic, especially in conditions where visibility may be compromised due to weather or road conditions.

In contrast, ignoring the stopped vehicle and continuing to drive poses a significant hazard, as you could inadvertently collide with it if there are no other alerts. Excessively honking your horn can cause confusion or panic, and it does not effectively communicate the situation to other drivers. Speeding up and attempting to pass poses a danger, as it might lead to an unexpected encounter with the obstructed vehicle or impede your ability to assess the conditions safely. Thus, using reflective triangles is the most responsible and effective way to ensure safety in such situations.
