What to Do
Watch for bridge signals, gates and stopped traffic and be prepared to stop.
A Detail to Remember
The raised bridge deck is the recognition clue; this is different from a narrow-bridge warning.
Understanding Warning Signs
Yellow warning signs ask you to anticipate a condition ahead. Read any distance or speed plaque with the main symbol, then adjust to what you can actually see on the road.
