How should drivers respond to a sign indicating 'No Left Turn'?

Answer: B — Look for an alternate route

When a driver encounters a 'No Left Turn' sign, the appropriate response is to look for an alternate route. This sign specifically prohibits making a left turn at that intersection, and drivers must adhere to this traffic rule to ensure safety and compliance with local regulations. Choosing an alternate route allows the driver to find a safe and legal way to reach their destination without violating traffic laws. It’s essential for drivers to be aware of their surroundings and plan their routes ahead of time to avoid illegal maneuvers, such as turning where prohibited or making u-turns that could create hazards or traffic issues. Ultimately, following the signage is crucial for orderly traffic flow and safety on the road.
