What to Do

Scan the junction for entering traffic and vehicles preparing to turn.

A Detail to Remember

This artwork has no HIDDEN plaque. The sign identifies the junction layout without that additional visibility message.

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.
