What type of location is indicated by a blue service sign with a gas pump icon?

• A. Parking lot
• B. Rest area
• C. Restaurant
• D. Gas station

Answer: (D)

Blue service signs guide drivers to available amenities along the road, and the gas pump icon specifically signals a gas station where you can refuel. The pictograph is chosen to be instantly recognizable, so you know at a glance that fuel is available there. Other service icons use different images—parking would be a P, rest areas show a resting figure or similar symbol, and restaurants use a fork and knife—so the gas pump clearly points to fueling facilities rather than those other services. This helps travelers quickly decide where to stop for fuel, especially on long trips.
