Signs in this lesson
Explanation
Warning signs prepare drivers for upcoming road conditions and hazards. Diamond-shaped signs give the same kind of warning. Among the manual’s warning signs, these name something about the road itself:
- Lanes: Added Lane, Lane Ends, Lanes Shifting, Merging Traffic.
- Road layout: Intersection Ahead, Side Road, “T” Intersection, Divided Highway Begins, Two-Way Traffic.
- Curves and hills: Curve Ahead, Sharp Turn Slow Down, Winding Road, Steep Downgrade.
- Surface and edges: Slippery When Wet, Watch For Ice On Bridges, Low Shoulder, Narrow Bridge.
- Clearance and objects: Low Clearance, Object Markers.
Example
A Lane Ends sign appears ahead. It is a warning sign: it prepares you for the upcoming road condition — the lane ending — before you reach it.
Common mistake
Ignoring a warning sign because it doesn’t state a rule. Warning signs exist to prepare you for upcoming road conditions and hazards.
