Req 5b — Reading Signs, Signals, and Markings

Drivers do not have time to read long explanations at 45 or 65 miles per hour. That is why road communication uses color, shape, symbols, and line patterns that can be recognized almost instantly. A good driver reads this visual language without hesitation.

Why color and shape matter

Colors and shapes act like shortcuts for the brain.

• Red usually means stop, prohibition, or wrong way
• Yellow warns of caution or a changing road condition
• Orange signals work zones and temporary hazards
• Green gives direction information
• Blue often points to services
• Brown usually marks parks or recreation sites

Shapes matter too. For example, an octagon means stop, a triangle points to yield, and a diamond means warning. A driver can often recognize the sign’s purpose before reading any words at all.

Types of traffic control devices

Regulatory signs tell road users what they must or must not do. Speed limits, stop signs, no-turn signs, and one-way signs fit here.

Warning signs alert drivers to something ahead, such as curves, merging traffic, deer crossings, or slippery roads.

Guide signs provide directions, routes, exits, and destination information.

Traffic signals control who moves and who waits at intersections, crosswalks, and some ramps.

Pavement markings organize lanes and show boundaries, turns, no-passing zones, stop lines, and crosswalks.

Pavement markings to notice

• Solid center lines often mean no passing or extra caution
• Broken lines usually mean lane changes or passing are allowed when safe
• Edge lines help define the roadway at night and in poor weather
• Arrows show permitted turn directions
• Crosswalk markings show where drivers should expect pedestrians

The next requirement moves from reading the road to sharing it with people who may be harder to see and easier to hurt: bicyclists, pedestrians, schoolchildren, and drivers around large vehicles.
