What is the role of speed cameras?

• A. They monitor seatbelt usage.
• B. They enforce speed limits by detecting speeding violations and issuing notices.
• C. They detect red-light violations.
• D. They record weather conditions.

Answer: (B)

Speed cameras exist to improve road safety by enforcing speed limits. They measure a vehicle’s speed as it passes or travels between points, and when the limit is exceeded, evidence is recorded and a notice or fine is issued to the vehicle’s owner. This deters speeding and helps reduce crash risk.

This differs from red-light cameras, which target running intersections, or from devices that check seatbelt use or record weather conditions, which aren’t functions of speed cameras.
