5.2.1 Baggage and equipment tractors shall be equipped with seated driver accommodation.
5.2.2 The operator’s seat shall be so located that the operator has sulficient room while operating the baggage or equipment tractor so as to remain within the plan view outline of the tractor. The dimensions shall be of suitable and ergonomic shape to accommodate at least a 5th percentile to a 95th percentile of the population, as shown in EN ISO 3411:2007, Figures 1 to 3, within the plan view outline of the truck The seat shall not extend beyond the plan view outline of the tractor.

b) be latched in the protective position;
c) prevent the whole body of the operator passing through the lateral opening;
d) withstand a horizontal effort of 450 daN applied at the most unfavourable point without unlatching.
5.2.5 An access gate fixed on both ends or a fully enclosed cabin with doors, both complying with the requirements of 5.2.4 are considered as a restraint system.
5.2.6 Warnings on the use of lateral restraint systems shall be provided and visible in the tractor. Actions to be taken to reduce the risk of a tip-over shall be described in the instruction manual, see 6.3.
