Bus Operating Requirements

The essentials

This topic presents the general idea of special safety requirements related to bus construction and operation. Attention is focused on passenger safety, doors, equipment and technical conditions important for public transport.

What to remember

Safe boarding and alighting, doors being closed while moving, permitted passenger capacity and proper operation of technical equipment are important in bus operation. Because a bus is large and stops frequently, it requires more space and predictable maneuvers. Specific exam requirements may differ from those for an ordinary passenger car.

The correct answer is “The tires have localized damage exposing the tire carcass (cord).”. The exact component condition and permitted limit are decisive; technical requirements differ by system. Remember the exact component and limit; numbers and conditions are decisive. The other options do not describe the exact condition or limit selected by the source as prohibiting operation in this task.

Operation of buses is prohibited if:
  1. A first aid kit is missing.
  2. The tread depth of the tires is 2.2 mm.
  3. In both cases.
