What do blue signs typically describe?

1. Traffic commands

2. Services for motorists

3. Speed regulations

4. Construction zones

The correct answer is: Services for motorists

Blue signs are used primarily to indicate services available to motorists. These services may include information about nearby hospitals, gas stations, rest areas, and food establishments. The use of blue for these signs helps drivers quickly locate essential services essential for travel and safety on the road. The distinction of blue signs as indicative of services distinguishes them from other types of signs. For example, traffic commands would typically be indicated by red or white signs, which explicitly convey regulations that drivers must follow. Speed regulations are commonly indicated by black and white signs to mark legal speed limits, while construction zones often use orange signs to alert drivers of temporary changes or hazards in the roadway. By understanding this color coding system, drivers can more effectively navigate and respond to various road situations.
