Question about whether all wheel drives can be trailers
Too fast, too long, too bad...... As for the division of responsibilities, this is hard to say. If you are listening to the parking in the road, now is not allowed because of the trailer, differential, before too many broken hand brake, gear box, which caused a lot of unnecessary loss. If this is the case, you can identify and find the trailer unit for economic losses compensation
Full time four wheel drive can not be long or more than 20 kilometers per hour traction, and if bogged down in a quagmire, short distance traction, within 20 km speed, there is no problem. If forced trailer, more than the limit, the most direct is to play a differential differential, the differential dry wear
If you stop in the fire lane, the hospital emergency passage, the city government gate, and some know that the stop is a "dead" place, then there is no way, in this case, is allowed to be forced trailer. There are many details, you still ask the legal friends, I do not define the details in detail.
