Under what circumstances can you use a lane marked "No Turn"?

Answer: C — It is always illegal to turn

A lane marked "No Turn" is specifically designated to prohibit any turning movements for vehicles. This means that regardless of the time of day, traffic conditions, or the actions of other drivers, turning from that lane is not permitted under any circumstances. The signs or road markings put in place signal a legal restriction, and following these signs is crucial for maintaining safe and orderly traffic flow. Turning from a lane where turning is explicitly prohibited can lead to confusion, accidents, and traffic violations. Therefore, understanding that it is always illegal to turn from a lane marked "No Turn" is essential for all drivers to ensure compliance with traffic laws and to promote safety on the road.
