This lesson details the default speed limits for cars in Great Britain. You will learn the 30 mph limit for built-up areas, 60 mph on single carriageways, and 70 mph on dual carriageways and motorways. It also covers how to identify these roads and the importance of looking for signs indicating a different limit is in force.
This lesson explains that safe driving often requires travelling at a speed lower than the legal limit. It covers how to adjust your speed for adverse conditions such as rain, which can double your stopping distance, or fog, which severely reduces visibility. The goal is to always be able to stop safely in the distance you can see to be clear.
This lesson breaks down the concept of stopping distance into its two key parts. Thinking distance is the distance travelled while you react to a hazard, while braking distance is the distance the car travels after you apply the brakes. You will learn how speed, weather, and vehicle condition influence these distances.
This lesson teaches a practical method for maintaining a safe distance from the vehicle in front. The 'two-second rule' provides a minimum time gap in dry conditions, which should be doubled to four seconds in the wet. Adhering to this rule gives you sufficient time to react and brake safely if the vehicle ahead stops suddenly.
This lesson introduces the skill of hazard perception, a critical component of the official theory test and safe driving. It teaches you to actively scan your environment for potential dangers, such as a pedestrian about to cross or a car waiting to emerge from a junction. By identifying these situations early, you can take action to avoid them turning into actual dangers.

In Great Britain, national speed limits vary by road type. For single carriageway roads, the limit is generally 60 mph for cars. On dual carriageways, it's 70 mph, and this also applies to motorways for cars. However, these limits can be lower in built-up areas, which are typically 30 mph, and specific signs will always indicate lower limits. Always check the signs as they may vary.
Stopping distance is the total distance a vehicle travels from the moment a hazard is seen to the moment the vehicle stops. It's made up of two parts: thinking distance and braking distance. Thinking distance is the distance travelled during your reaction time (typically 2 seconds). Braking distance is the distance the car travels once the brakes are applied. Your total stopping distance is the sum of these two.
Several factors can significantly increase your stopping distance. These include driving at higher speeds (braking distance increases with the square of the speed), poor road conditions (e.g., wet, icy, or oily surfaces), worn tyres, and the condition of your vehicle's brakes. Also, if you are tired, under the influence of alcohol or drugs, your reaction time (thinking distance) will increase.
Hazard perception is the ability to identify potential dangers or situations that could lead to an incident while driving. For the theory test, it's crucial because a significant part of the exam assesses your ability to spot developing hazards in video clips. In real driving, good hazard perception allows you to anticipate risks and react safely, often preventing accidents before they happen.
Practice hazard perception by actively scanning the road ahead when you're a passenger or practicing your driving. Look for clues like brake lights, pedestrians near the kerb, or vehicles emerging from junctions. Our app provides interactive hazard perception clips that simulate the test environment, helping you identify developing risks and score effectively.
The 'two-second rule' is a simple method to maintain a safe following distance from the vehicle in front. When the vehicle ahead passes a fixed point (like a signpost), start counting 'one-thousand-and-one, one-thousand-and-two'. If you pass the same point before you finish counting, you are too close. This rule should be extended to four seconds or more in adverse conditions like rain, fog, or ice.
