When is it ok to travel with a load raised more than a few inches?

It is generally acceptable to travel with a load raised more than a few inches only when necessary for safe clearance or visibility.

Additionally, it is crucial to operate at reduced speeds and be aware of the surrounding environment to prevent accidents. Always follow the specific safety guidelines and regulations provided for the equipment being used.
