By signing that document and checking the statement that the van is in good condition to operate safely, youu2019re saying that if you get into an accident, the fault is yours because the van is safe and operational. Youu2019d be completely liable.The same applies if you state the vehicleu2019s brakes are operational and another driver in that vehicle were to rear-end someone, stating the brakes fails. Once again, youu2019d be liable because your report said the brakes were safe to operate the vehicle with.Your best advice is to either not sign the document or make a note that the breaks are not optimal before signing. You may also want to make a copy of the document for your own records.If itu2019s not safe, donu2019t sign.
