Your overall stopping distance will be much longer when driving

A in the rain

Extra care should be taken in wet weather as, on wet roads, your stopping distance could be double that necessary for dry conditions.

Thinking distance:

The distance travelled between the realisation of the need to brake and the time it takes to use the brakes is referred to as the thinking distance. Thinking distance is roughly one foot for every mph of travel. For example, if you're driving at 30 mph, your thinking distance is about 30 feet.

Braking distance:

Braking distance is the distance your automobile travels after you apply the brakes until it comes to a complete stop. The more your speed, the more momentum you have, and the greater your braking distance.

Stopping distance:

The entire distance you travel before applying the brakes, plus the distance you travel while the brakes slow you down, is the stopping distance.

Thinking distance+ braking distance = overall stopping distance.

It's important to note that the estimated stopping distance calculation assumes the driver is not distracted or drunk, is driving a well-maintained car, and is driving in normal, dry road conditions.

What affects overall stopping distances?

Always keep in mind that your vehicle's overall stopping distance is greatly influenced by a variety of factors, including:

- The speed at which you travel. If you're going fast, you'll need to give yourself extra time to stop.

- Whether you're on a flat course or a hill that's heading up or down, as well as the steepness of the hill.

- Weather; is it nice and dry, or is it wet and icy? 

- Tyres; are they in excellent condition and correctly inflated, or are they worn and underinflated?

- Are your brakes operating properly and stopping you in a straight line?

- Your driving ability. Are you sick, fatigued, on medication, have you had alcohol, or are you distracted? All of these things might have an impact on your reactions while using the brakes.

Keep in mind that being distracted while driving will cause you to lose attention on the road.

Using a cell phone while driving is forbidden for a reason, but you should avoid fiddling with the radio, heating or air conditioning, and sat-navs.

Then there's the distraction of other passengers, whether they're friends or relatives!

Brilliant for the multiple choice bit of the theory. Never looked at the highway code, just went through all of the practice questions in this (free version) over a few hours and passed my test 48/50.
