DDifficulty 3/5

For a three-axle articulated bus using conventional fuel, without alternative-fuel or zero-emission allowances or special authorisation, what is the general Annex IX mass maximum, subject to lower technical or specific limits?

Correct answer

28 tonnes.

28 tonnes in the stated case. This is the category’s general maximum, not necessarily the authorised mass of every articulated bus or a guarantee of stability or braking. Also observe the specific vehicle’s authorised mass, axle limits and any applicable lower limit. Regulatory allowances for certain technologies are excluded from the question; they do not authorise exceeding other requirements.
