Coach Loading, Axle Limits and a Blocked Emergency Exit
You are loading a 49-seat coach for a school tour. There are 46 passengers, mostly teenagers, and luggage is carried in the underfloor hold. A weighbridge ticket shows: front axle 6,800 kg against a plated limit of 7,100 kg; rear axle 11,200 kg against 11,500 kg; gross vehicle weight 17,900 kg against 18,000 kg. A teacher asks you to add eight heavy suitcases, about 25 kg each, to the rear hold because the front hold is full. In the aisle there are two folded buggies and a cool box; the rear emergency exit is partly blocked by a rucksack. The tour operator says the coach always runs a bit heavy and that the weighbridge is only a guide. The next weighbridge is 40 km away.
1. Calculate the effect of adding the eight suitcases and decide whether you can depart.
Read the worked answer
Eight cases at about 25 kg add 200 kg. The rear axle would be about 11,400 kg, which is inside the 11,500 kg plated limit by only 100 kg, but the gross weight would be about 18,100 kg against an 18,000 kg limit. That is 100 kg over, so you cannot depart as loaded. Because the cases go into the rear hold, the rear axle could gain more than 200 kg if they sit behind the axle, so the 100 kg margin is not reliable. The weighbridge ticket is a legal limit, not a guide. Remove or redistribute at least 100 kg, secure the load, and reweigh before departure; do not rely on the next weighbridge 40 km away.
2. What are the loading rules about the aisle and emergency exit?
Read the worked answer
The aisle and emergency exits must be kept clear. Folded buggies and a cool box in the aisle can trip passengers during an evacuation, and a rucksack partly blocking the rear exit could stop the door opening fully. Put them in the hold only if the weight and securing are correct, or leave them behind. Luggage must be secured so it cannot move in braking. The driver is responsible for the load, not the teacher or tour operator. Before departure, walk the aisle, check both exits, and confirm that nothing can fall or block the way out.
3. What would you say to the teacher and operator?
Read the worked answer
Explain that the coach is over its gross weight limit and that the aisle and exit are obstructed, so it cannot legally or safely leave. Offer practical options: leave the eight cases, move other items to balance the load, arrange a second vehicle, or send the cases separately. Do not accept the argument that the coach always runs heavy. Record the decision and the weights. If the operator insists, refuse to drive and escalate. The safety of 46 passengers and other road users outweighs the tour timetable.
