This lesson provides a clear overview of the statutory speed limits applicable on various types of roads in Portugal. It covers the default limits for built-up areas, single carriageways, dual carriageways, and motorways. Understanding these legal maximums is the first step in managing speed effectively and avoiding penalties for speeding.
This lesson teaches the crucial skill of selecting a safe and appropriate speed that considers the prevailing conditions. It explains why the legal speed limit is often not the safest speed in adverse weather, heavy traffic, or poor visibility. Drivers will learn to assess the environment and modify their speed to maintain control and allow for adequate stopping distance.
This lesson introduces the 'two-second rule' as a simple and effective method for establishing a safe following distance in good driving conditions. It explains the rationale behind this rule, linking it directly to average reaction and braking times. The lesson also emphasizes the need to extend this gap to three or more seconds in wet, icy, or low-visibility situations.
This lesson breaks down the concept of total stopping distance into its two key parts: the distance travelled during the driver's reaction time (thinking distance) and the distance the vehicle travels while braking. It explains how factors like speed, driver alertness, tyre condition, and road surface dramatically influence these distances. This knowledge is vital for understanding the consequences of driving too fast or too close.
This lesson introduces the principles of hazard perception, a key skill for proactive and defensive driving. It teaches techniques for systematically scanning the environment, identifying potential risks before they develop into immediate dangers, and planning escape routes. By improving their ability to anticipate the actions of others, drivers can significantly reduce their risk of being involved in a collision.

Reaction time is the duration it takes for you to perceive a hazard and initiate the braking action. Braking distance is the distance your vehicle travels from the moment you apply the brakes until it comes to a complete stop. Total stopping distance is the sum of both.
The two-second rule involves picking a fixed object (like a sign or bridge) that the vehicle in front passes. Start counting 'one-thousand-one, one-thousand-two'. If you pass the same object before finishing your count, you are too close. This ensures a safe buffer on dry roads.
Several factors affect stopping distance. These include your vehicle's speed (higher speed significantly increases braking distance), road conditions (wet or slippery surfaces increase it), tyre condition, and brake efficiency. Your reaction time can also vary based on fatigue or distractions.
Hazard perception is crucial because it assesses your ability to recognize potential dangers on the road and react effectively before a situation becomes critical. A high level of hazard perception indicates you are likely to be a safer driver, which is a key focus of the IMT's assessment.
Yes, absolutely. In adverse weather conditions like rain, fog, or ice, road surfaces become slippery, significantly increasing your braking distance. You should increase your following distance to at least three or four seconds to allow for this extra stopping distance and give yourself more time to react.
You can practice hazard perception by actively scanning the road environment during your lessons and while driving. Look for potential risks like pedestrians near crossings, cyclists, vehicles emerging from side roads, or changes in traffic flow. Our app also provides specific lessons and exercises designed to train your hazard recognition skills for the exam.
