This unit focuses on the critical physical aspects of controlling your moped safely. You'll learn how to manage speed effectively, apply brakes correctly in all situations, and understand the vital role of tire grip and traction, especially when cornering. Mastering these elements is key to passing your AM theory exam and ensuring safe operation of your light quadricycle or moped on Portuguese roads.

Browse all lessons that make up Speed, Braking, Grip and Small Vehicle Control. Each lesson focuses on specific topics, learning objectives, and core concepts, helping you build essential knowledge and follow a clear, structured progression toward your study goals in Portugal.
This lesson focuses on the critical skill of managing speed within complex urban settings. It explains that driving at the speed limit is not always the safest option and teaches riders how to adjust their speed based on traffic density, pedestrian activity, and visibility. The content reinforces the principle of always being able to stop safely within the distance you can see to be clear.
This lesson breaks down the concept of total stopping distance into thinking distance and braking distance. It provides instruction on how to use both front and rear brakes effectively and progressively to slow down smoothly and safely. The content also covers techniques for performing an emergency stop while maintaining control and how braking is affected by wet or loose road surfaces.
This lesson explains the physics of how tires maintain grip with the road surface, a crucial concept for two-wheeled vehicles. It details the correct technique for cornering, which involves adjusting speed before the turn, selecting a safe line, and leaning the vehicle. The content also discusses common causes of grip loss, such as poor road surfaces or improper rider inputs.
This lesson focuses on the specific skills needed for controlling a moped at very low speeds, such as in heavy traffic or when making tight turns. It explains how to maintain balance through a combination of subtle throttle, clutch, and rear brake inputs. The importance of looking where you want to go and maintaining a relaxed but correct posture is also emphasized for maximum stability.
This lesson teaches riders how to assess and adapt to the increased risks associated with adverse weather and road conditions. It explains how rain reduces tire grip and visibility, requiring lower speeds and gentler control inputs. The content also provides advice for dealing with other challenging conditions such as strong crosswinds, fog, and road surface hazards like potholes or gravel.

Find clear answers to the most common questions learners ask about Speed, Braking, Grip and Small Vehicle Control. Understand how the unit is organized, what learning goals it supports, and how it contributes to your study progression with structured explanations and practical guidance tailored for learners in Portugal.
Higher speeds dramatically increase stopping distance. As speed doubles, the stopping distance roughly quadruples. This unit explains the physics behind this and why maintaining appropriate speeds, especially in Portugal's varied traffic conditions, is crucial for safety. You'll learn how to calculate safe following distances based on speed.
Effective braking involves using both front and rear brakes simultaneously and progressively. The front brake typically provides more stopping power, but it's essential not to lock the wheel. This unit details how to apply optimal pressure for normal stops and emergency situations to maximize stopping power while maintaining control.
Tire grip, or traction, is what allows your moped to accelerate, brake, and turn without sliding. Understanding how grip works, how it changes with road conditions (like wet or gravel surfaces), and how it relates to cornering forces is fundamental to safe riding. This unit explains these principles to help you maintain control.
You must always adjust your speed to suit the conditions, not just the posted limit. This means slowing down for rain, fog, ice, gravel, or poor road surfaces where grip is reduced. This unit covers specific advice on how to assess conditions and modify your speed to ensure safety and control.
Yes, absolutely. The unit explains the dynamics of cornering, including the interplay between speed, lean angle, and tire grip. Understanding these concepts will help you answer questions related to safely navigating bends and roundabouts, a common topic in the Portuguese AM theory exam.
Relying solely on the rear brake can lead to instability and skidding, especially during hard braking. Over-reliance on the front brake without proper technique can cause the front wheel to lock, resulting in a loss of steering control and a potential fall. This unit teaches the balanced approach.
