Why are blocking vehicles parked at an angle?

Blocking vehicles are parked at an angle primarily so that approaching drivers can easily see that the blocking vehicle is stopped and parked. When these vehicles are angled, they create a visual cue that alerts drivers to the presence of a situation requiring caution or diversion. This positioning helps enhance visibility, particularly in low-light situations or during adverse weather conditions.

The angled parking also allows for a better sightline, making it easier for drivers to recognize the blockage well in advance, enabling them to reduce speed and maneuver safely around the incident. Enhanced visibility can be crucial in preventing further accidents and ensuring the safety of responders and motorists alike in traffic incident scenarios.
