Vehicles carrying explosive substances or flammable liquids must reduce speed to how many miles per hour or less when near a railroad?

When vehicles transporting explosive substances or flammable liquids approach a railroad, they are required to reduce their speed to 20 miles per hour or less. This regulation is designed to enhance safety by ensuring that drivers have sufficient time to react to potential hazards, such as a train approaching the crossing. At this reduced speed, drivers can better navigate the crossing and increase the likelihood of safely clearing the tracks without endangering themselves or others.

The requirement for this specific speed limit reflects the increased risks associated with carrying hazardous materials, emphasizing the need for caution in these situations. Adhering to this speed limit can significantly help prevent accidents and ensure the safe transportation of dangerous goods.
