# Explanation: Deceleration Lane
The deceleration lane is an additional stretch of road located at the end of motorways that allows drivers to gradually reduce their speed safely before leaving the fast road. This lane provides sufficient distance to brake without affecting traffic continuing on the motorway. It is especially important at motorway exits to avoid sudden braking that could cause accidents.
