Traffic order and driving through intersectionsQuestion #16504
Where must you slow down if there is a deceleration lane?
Explanation
You should slow down in the deceleration lane itself, not in the main carriageway. A driver planning to turn off should move into the deceleration lane as early as possible and brake there. That is what the lane is for — so a turning car can slow down without holding up the main flow of traffic.
KET reference: KET 111: a driver intending to turn must move into the deceleration lane as early as possible and slow down in it.
