The maximum distance a load may overhang your vehicle behind the rear axle generally depends on local regulations. One common standard is that a load can extend up to 4 meters behind the rear axle. If the load protrudes more than 1 meter behind the vehicle, a fluorescent flag must be tied to the end of the load to make it visible.
In some regulations, this rear overhang is also described as the lesser of 3.7 meters or 60% of the vehicle's wheelbase for rigid trucks and similar vehicles, with specific variations for trailers and vehicle carriers.
Thus, the typical maximum overhang behind the rear axle is around 4 meters, but it can be limited further by being a percentage of the vehicle's wheelbase or specific vehicle type restrictions.
