Never allow a person to ride in the boot:
Allowing a person to ride in the boot is dangerous. The person in the boot could be seriously injured or killed during sudden braking or a collision.
Do not drive with the boot lid open:
Exhaust gas in the cabin of a vehicle is dangerous. An open boot lid in a moving vehicle will cause exhaust gas to be drawn into the cabin. This gas contains CO (carbon monoxide), which is colourless, odourless, and highly poisonous, and it can cause loss of consciousness and death. Moreover, an open boot lid could cause occupants to fall out in an accident.
Before opening the boot lid, remove any snow and ice accumulation on it. Otherwise, the boot lid could close under the weight of the snow and ice resulting in injury.
Be careful when opening/closing the boot lid during strong winds. If a strong gust blows against the boot lid, it could close suddenly resulting in injury.
Fully open the boot lid and make sure that it stays open. If the boot lid is only opened partially, it could slam shut by vibration or wind gusts resulting in injury.
When loading or unloading luggage in the boot, turn off the engine. Otherwise, you could get burned by the heat of the exhaust gas.
