Learn to identify signs that warn about the physical condition of the road itself or structures on it, such as narrow bridges, low clearances, and changes in pavement.
What change in road surface does this sign warn of?
The paved surface ends ahead and the road will become a gravel or dirt surface. Slow down before reaching the new surface as vehicle control and traction will be reduced.
What does a 'DIP' sign warn you about?
There is a sharp, low spot in the road ahead. Slow down to avoid losing control or damaging your vehicle's suspension when you cross it.
What does this 'Narrow Bridge' sign indicate?
The bridge ahead is narrower than the road you are on. Slow down, check for oncoming traffic, and make sure there is enough space to pass safely.
Who must pay special attention to this 'Low Clearance' sign?
Drivers of tall vehicles like trucks, RVs, and buses. It indicates the maximum safe vertical height to pass under an overpass or structure, shown in feet and inches.
How is a 'BUMP' different from a 'DIP'?
A 'BUMP' is a raised area in the road, while a 'DIP' is a low area. Both are potential hazards that require you to slow down to maintain control and avoid vehicle damage.
What does a 'ONE LANE BRIDGE' sign mean?
The bridge ahead is only wide enough for one vehicle at a time. You must yield the right-of-way to any traffic already on the bridge or that arrives before you.
