For vehicles manufactured in 1960 or newer, how many stop lamps are required?

Vehicles manufactured in 1960 or newer are required to have two stop lamps. This requirement is part of the federal regulations aimed at ensuring safety on the road. The presence of two stop lamps provides better visibility for drivers behind the vehicle, enhancing communication regarding the vehicle's braking actions.

This specific regulation is important because having two stop lamps helps reduce the likelihood of rear-end collisions by making it clearer to other drivers when the vehicle is slowing down or stopping. This standard was established to improve road safety, which is why any vehicle manufactured after 1960 must comply with the two-stop lamp rule to be legally drivable on public roads.
