Lesson 4: Progression management
EDT lesson 4 is about controlling the speed of the car so you make steady, sensible progress. That means not too fast for the conditions, and not so hesitant that you hold others up or miss safe gaps.
The RSA booklet says this lesson should take place in lower-risk settings, such as quiet residential areas and rural roads.
By the end of this topic you can
- You can control your speed smoothly with the accelerator, gears and brakes
- You can keep within the speed limit and choose a lower speed when conditions need it
- You can explain how road surface, weather and the car's load change stopping distances
- You can explain the risks of driving too fast and braking too hard
- You can move off and take safe gaps without undue hesitation
What you need to know and understand
- A speed limit is the most you may drive, not a target.
- Stopping distance is your thinking distance plus your braking distance, and it grows quickly as speed rises.
- Wet, icy or loose road surfaces increase braking distance.
- A heavily loaded car takes longer to stop.
- Driving too fast and braking hard put you, your passengers and other road users at risk, and waste fuel.
- Progress is assessed on the driving test, and inadequate progress at junctions, such as not taking a safe gap, is one of the RSA's common reasons for failing.
What the session covers
The RSA sets out the minimum content for this lesson as controlling speed, speed limits, stopping distances, the effects of road and weather conditions, and the dangers of driving too fast.
Your ADI will watch how you use the accelerator and brakes, how you plan ahead to avoid sudden braking, and whether you pick up speed again sensibly after a hazard.
Smooth speed control in practice
- Look well ahead so you see bends, junctions and hazards early.
- Ease off the accelerator first, letting the car slow gently.
- Brake progressively: light at first, firmer if needed, then ease off as you stop.
- Choose the right gear for your new speed.
- When the way is clear and it is safe, build speed back up to suit the road.
Too fast versus too hesitant
Afterwards the RSA suggests about three hours of practice on correct speed in different situations, plus reading the Rules of the Road on speed and stopping distances.
- Too fast: taking bends or junctions at a speed that leaves no margin for error
- Too fast: having to brake hard because you noticed a hazard late
- Too hesitant: waiting at a junction when there is a clear, safe gap
- Too hesitant: driving well below a sensible speed on a clear road for no reason
Common mistakes
- Treating the speed limit as the speed you should drive. Match your speed to what you can see and the conditions.
- Braking late and hard. Read the road ahead so you can slow gradually.
- Freezing at junctions. Judge gaps in good time and go when it is safe.
- Forgetting that rain and a full car both add to stopping distance.
