# Explanation: Deceleration Lane on Dual Carriageways You must enter the deceleration lane **as soon as possible** when you see the exit signage. This allows you to reduce speed safely and in a controlled manner without affecting traffic on the dual carriageway. Entering the deceleration lane late reduces the space available to brake and increases the risk of accidents.
