Is it permissible to drive the car on a public road?
“If a motor vehicle or a vehicle coupled to this has a load where either side protrudes more than 20 centimetres outside the vehicle, or if the vehicle’s width, including load, exceeds 260 centimetres, [...] the vehicle or a vehicle coupled to this may only be driven on a private road.” (Road Traffic Ordinance)
Review of the options:
No, since the width is 260 cm. – Wrong, the width may be exactly 260 cm, but not more.
No, since the load protrudes 40 cm on one side. – Correct according to the quote from the Road Traffic Ordinance.
Yes, since the width does not exceed 260 cm. – Wrong, since the option indicates that it is permitted to drive the car with this load.
Yes, since the load does not protrude at all on the other side. – Wrong, since the option indicates that it is permitted to drive the car with this load.
