Slow-moving traffic

Rule 151

In slow-moving traffic. You should:

• reduce the distance between you and the vehicle ahead to maintain traffic flow
• never get so close to the vehicle in front that you cannot stop safely
• leave enough space to be able to manoeuvre if the vehicle in front breaks down or an emergency vehicle needs to get past
• not change lanes to the left to overtake
• allow access into and from side roads, as blocking these will add to congestion
• be aware of cyclists and motorcyclists who may be passing on either side
