On the marina driveway in Heeg your load sticks out 1.2 m behind your trailer. You hang a square, red-and-white striped board of 45 by 45 cm on it, with its lower edge 0.30 m above the road. A neighbour says this is not allowed.
Get a bigger board, it must be 50 by 50 cm
Set off like this, the size and height of this board are fine
Get another board, it should be blue and white
Explanation
False — You take the shop size for the legal size. A square rear board must be at least 42 by 42 cm; 50 by 50 cm is only a common size, so 45 by 45 cm is fine. (VekaBest p.229-230; Regeling voertuigen art. 130-132)
