Total mass and a separate carrier limit

A fictional vehicle has a permitted maximum mass of 400 kilograms and an initial mass of 190 kilograms. Two occupants add 82 and 68 kilograms, while luggage adds 36 kilograms in total. One luggage carrier is limited by its actual manufacturer to 7 kilograms, but 20 kilograms of the luggage are placed there. The model is an explicit loading exercise rather than a statement of the actual statutory limits for any German licence class. It supplies no axle values, restraint approval or permission to carry the occupants. A learner observes the acceptable overall mass and says every part of the arrangement must therefore be acceptable. Another distinguishes the total from the carrier condition. A correct answer computes both results without assuming that simply moving the luggage automatically establishes every other requirement.

1. Compute total and carrier excess.

Read the worked answer

Total is 190+82+68+36=376 kg, below the stated 400 kgmaximum. The carrier is overloaded by 20−7=13 kg despite the acceptable total.

2. What remains after changing the carrier load?

Read the worked answer

The actual axle distribution, other attachments, restraint, vehicle permissions and equipment requirements still need assessment. Correcting one limit does not establish all others.
