23. Railway crossing

A railway crossing, also called a level crossing or railroad crossing, is a place where a road or path crosses railway tracks at the same level. It may be protected by barriers, warning lights, bells, traffic signs or a combination of these measures.

Road users must approach carefully and never enter when a train is approaching, warning signals are active or the exit is blocked. They should cross promptly and must never stop, wait or become trapped on the tracks.

When must drivers stop at a railroad crossing in United States?

In California, stop for an approaching train or an active crossing warning and obey STOP signs and railway personnel. Do not go under lowering gates or around closed gates. Specified buses and vehicles carrying hazardous materials have additional mandatory stopping duties. Other states have their own detailed rules.

Must I stop at every unguarded railway crossing in United States?

There is no single rule for every US state. In California, missing barriers alone do not require every ordinary car to stop: obey STOP signs, train warnings and the duty to stop for approaching rail traffic. Specified buses and hazardous-material vehicles have additional stopping duties. Look and listen carefully before crossing.

What if road traffic is queued beyond a railway crossing in United States?

In California, do not enter until there is enough space for your entire vehicle beyond the tracks. Check the exit before following another vehicle and never stop on the tracks. Follow the applicable state rules elsewhere in the USA.

Can I cross after a train has passed if the warning lights are still active in United States?

In California, no. Wait until the red warning lights stop flashing, even if the gate has started to rise, and cross only when the gate is clear and it is safe. Another train may be approaching. Follow the applicable state rules elsewhere.
