The Ghana Driver's Guide groups road signs into three main categories:
Regulatory signs give orders that must be obeyed. Failing to follow them is a traffic offence.
Shape
Usually circular
Color
Often have a red border
Style
Some are blue with white symbols
Examples: Stop, No entry, No U-turn, Speed limit signs, Give way
Regulatory signs override general traffic rules. If a sign says "No Parking," parking is illegal even if the road looks safe.
Warning signs alert drivers to danger or changes in the road ahead. They help drivers prepare and adjust speed.
Shape
Usually triangular
Color
Often have a red border
Purpose
Show symbols indicating danger
Examples: Sharp bend ahead, Pedestrian crossing, Slippery road, Junction ahead, Road narrows
Warning signs do not give orders — they warn you so you can drive carefully.
Informational signs provide guidance and useful information to road users.
Shape
Usually rectangular or square
Color
Often blue or green
Purpose
Do not impose restrictions
Examples: Hospital ahead, Parking area, Bus stop, Direction signs, Fuel station
These signs help drivers navigate safely and conveniently.
