How far before a stop should you activate alternating flashing amber lights within town or city limits?

Activating alternating flashing amber lights is an essential safety measure when a vehicle is approaching a stop, particularly in urban areas where traffic may be more congested and unpredictable. The correct answer indicates that the lights should be activated 200-300 feet or approximately 5-10 seconds before coming to a stop. This distance allows enough warning for vehicles behind you and for pedestrians, giving them time to react safely.

This practice enhances visibility and alerts other road users that the vehicle is preparing to stop, which is crucial in city driving. By activating the lights within this timeframe, you maintain a balance between providing adequate warning and ensuring that the approach to the stop is safe and orderly. This timeframe is manageable and effective in busier environments, where stopping situations can develop quickly.

The other options suggest either a greater distance or an immediate activation, which may not provide optimum safety or timing for city driving conditions. Activating the lights too late may not give enough time for other drivers to react, while activating them too soon could lead to confusion, especially in dense traffic.
