What is the visibility requirement for the warning devices used by disabled vehicles?

The visibility requirement for warning devices used by disabled vehicles is 500 feet in the dark. This regulation is designed to ensure that other drivers can see a disabled vehicle from a substantial distance, reducing the risk of collisions and enhancing safety on the road. The 500-foot requirement allows for adequate reaction time for motorists who may not expect to encounter a stopped vehicle, especially in low-light conditions.

While the other distance options may sound appropriate, they do not meet the specific legal standard established for these situations. The obligation to maintain a minimum visibility distance of 500 feet is intended to protect both the occupants of the disabled vehicle and other road users by promoting a safe driving environment.
