A truck or any vehicle towing another vehicle may not follow within __________ feet of another truck or vehicle towing a vehicle.

A truck or any vehicle towing another vehicle may not follow within 300 feet of another truck or vehicle that is also towing a vehicle due to safety regulations. This distance is set to reduce the risk of collisions and ensure adequate space for maneuvering. Following too closely can create dangerous situations, especially given that trucks and towing vehicles have longer stopping distances compared to standard passenger vehicles. The 300-foot rule helps ensure that drivers have enough reaction time to respond to sudden stops or emergencies from the vehicle ahead, thereby enhancing overall safety on the roads. The other distances specified do not provide the same level of safety or reaction time necessary to maintain safe driving conditions when towing.
