# Are you preparing for the Official DVSA Driving Theory Test but keep getting caught out by the questions on stopping distances, braking distances and thinking distances?

1. Understand the difference between thinking, braking and stopping distance:

 Thinking Distance Braking Distance Stopping Distance Thinking distance is the distance you travel between spotting the hazard and physically hitting the brake pedal. Braking distance is the distance you travel between hitting the brakes and actually coming to a stop. Stopping distances is both the thinking distance and the braking distance added together.

2. Be familiar with stopping distances at different speeds and in different road conditions:

### What is the stopping distance at...

 Speed Stopping Distance 20mph 12 Meters / 40 Feet 30mph 23 Meters / 75 Feet 40mph 36 Meters / 118 Feet 50mph 53 Meters / 175 Feet 60mph 73 Meters / 240 Feet 70mph 96 Meters / 315 Feet

### Wet and Icy Conditions

Wet conditions = Your braking and overall stopping distance will at least DOUBLE

Icy conditions = Your braking and overall stopping distance will be at least TEN TIMES

.3. Learn this handy trick on how to remember stopping distances

Here is a great way to remember the overall stopping distances.

Starting from 20mph you simply multiply the speed by intervals of 0.5, beginning with 2, for example, 2, 2.5, 3, 3.5 etc as follows:

 20mph x 2 = 40 feet ((12 meters) or 3 car lengths) 30 mph x 2.5 = 75 feet ((23 meters) or 6 car lengths) 40 mph x 3 = 120 feet ((36.5 meters) or 9 car lengths) 50 mph x 3.5 = 175 feet ((53 meters) or 13 car lengths) 60 mph x 4 = 240 feet ((73 meters) or 18 car lengths) 70 mph x 4.5 = 315 feet ((96 meters) or 24 car lengths)
