Lesson 8: Driving safely through traffic
EDT lesson 8 puts you into busier traffic, where you have to keep your care and attention while lots of other road users are around you. The focus is defensive driving, spotting risks to others and co-operating with other drivers.
It is the last of the core lessons 2 to 8. Once these are done you can move on to lessons 9 to 12.
By the end of this topic you can
- You can act appropriately and decisively while driving in traffic
- You can identify potential risks to other road users and respond effectively
- You can use defensive driving techniques without causing hesitation or holding up traffic
- You can co-operate well with other road users
What you need to know and understand
- Defensive driving means planning for other people's mistakes, not just your own.
- Decisive does not mean aggressive: it means making a clear, safe decision in good time.
- Being too hesitant in traffic can confuse others, and progress is one of the things assessed on the driving test.
- Letting others merge, keeping junctions clear and using signals properly all help traffic flow safely.
- Keep a safe gap even in slow, stop-start traffic.
- Learner permit holders may not drive on motorways, so lesson 8 uses busy town roads and main roads.
What defensive driving looks like
- Assume a car at a side road might pull out and be ready to slow
- Leave space around your car so you have an escape route
- Make eye contact with drivers and pedestrians when you can
- Avoid sitting in other drivers' blind spots, especially beside lorries and buses
- Signal clearly so your plan is never a surprise
Handling a busy multi-lane road
- Read the signs and lane markings early and get into the right lane in good time.
- Keep checking mirrors, as traffic beside and behind you changes quickly.
- To change lane: mirror, signal, mirror and safety glance, then move smoothly into a safe gap.
- If you miss your turn, carry on and find a safe place to correct your route. Never cut across lanes at the last moment.
Outcomes and preparation
The RSA's expected outcomes are that you act appropriately and decisively in traffic, identify potential risks to other road users and respond effectively, use defensive driving that does not cause hesitation or impede reasonable progress, and show a good level of co-operation.
To prepare, the RSA suggests about three hours of practice in busier traffic, plus reading the Rules of the Road sections on sharing the road and driving safely through traffic. Build up gradually: quiet times first, then busier ones.
Common mistakes
- Freezing in heavy traffic and stopping when it is not needed. Plan ahead so decisions are made early.
- Forcing into a gap that is too small. Wait for the next safe one.
- Staying alongside a large vehicle. Drop back or pass so you are visible.
- Last-second lane changes. Read signs early and accept a detour if you miss a turn.
