If the vehicle's rear sight is blocked, how many mirrors are required?

The requirement for mirrors on a vehicle, particularly when the rear sight is obstructed, is to ensure that the driver has adequate visibility to ensure safe operation. In Texas, if the vehicle's rear sight is blocked, it is mandated that at least two mirrors must be utilized to provide a clear view to the rear. This helps compensate for the impaired visibility and enhances safety by allowing the driver to monitor surroundings effectively.

Having two mirrors, typically one on each side of the vehicle, allows for a broader range of vision and minimizes blind spots, promoting safer driving conditions. This requirement aligns with regulations intended to ensure that vehicles are equipped to maintain the driver's awareness of their environment while driving. Thus, the answer reflects the importance of maintaining safety standards on the road.
