This lesson covers the dimensional limits for heavy vehicles, focusing on height, width, and length restrictions. It explains how to interpret clearance signage for bridges, tunnels, and overhead obstacles, and discusses the implications for route planning. The content also addresses the importance of understanding turning radii and swept paths to avoid collisions.
This lesson explains the concepts of permissible total mass and actual mass, as well as the risks and legal consequences of overloading. It discusses how exceeding mass limits can lead to fines, increased stopping distances, and a higher risk of instability. Additionally, the content highlights the impact of overloading on vehicle wear and legal liabilities.
This lesson focuses on the distribution of loads across axle groups and the legal limits for axle loads. It explains the importance of correct weight distribution to avoid axle overloading, which can lead to road damage and safety hazards. The content also covers methods for measuring axle loads and the legal requirements for maintaining proper axle load limits.
This lesson teaches how to calculate the payload and gross combination mass (GCM) for vehicle combinations. It explains the difference between vehicle mass and payload, and introduces the concept of tongue load and its impact on handling and braking. The content provides practical examples and calculation formulas for determining permissible loads for safe operation.
This lesson examines the specific height, width, and length constraints that affect heavy vehicle operation, including bridge and tunnel clearances. It discusses how to interpret and comply with traffic signs indicating dimensional limits and the consequences of violating these restrictions. The content also covers practical strategies for route planning to avoid restricted areas.

Find clear answers to the most common questions learners ask about Dimensions, Masses, Axle Loads and Operating Limits. 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 Germany.
The permissible total mass (zulässige Gesamtmasse) is the maximum legally allowed weight of the vehicle, including its own weight, fuel, driver, passengers, and cargo. The actual mass (tatsächliche Masse) is the vehicle's weight at any given moment, including its current load. It's crucial that the actual mass never exceeds the permissible total mass.
Axle load limits are critical because they protect road infrastructure from excessive wear and damage. Exceeding legal axle loads can lead to fines, points on your license, and potential vehicle damage. Proper distribution of weight across axles ensures stability and prevents exceeding these limits.
Vehicle dimensions – height, width, and length – are vital for route planning because they determine whether a vehicle can safely pass under bridges, through tunnels, or on narrow roads. Drivers must be aware of their vehicle's dimensions and consult route restrictions, especially when carrying oversized loads.
Overloading a heavy vehicle significantly increases braking distances, strains the suspension and tires, reduces maneuverability, and can lead to catastrophic component failure. It also poses a serious risk to other road users and results in severe legal penalties, including fines and license suspensions.
Gross Combination Mass (GCM), or 'Gesamtmassen', refers to the total permissible weight of a towing vehicle and its trailer(s) combined. It's calculated by adding the permissible total mass of the towing vehicle and the permissible total mass of the trailer(s), ensuring the total does not exceed manufacturer or legal limits.
Yes, this unit is specifically tailored to the German legal framework for heavy vehicles. It covers regulations found in the Straßenverkehrs-Ordnung (StVO) and related regulations concerning vehicle dimensions, permissible masses, and axle loads, directly preparing you for the official German theory test.
