Drive and have an accident when it is found your fault you should pay for all damages. What ever the cost may be. Drive drunk and have an accident which is found not your fault, (even though you were drunk) the other person should pay for damages, what ever the cost may be.
But that ain't gonna happen whether your a Spanish person or Canadian.
Hold on. A guy I work with has an ex-wife from Peru. She was drunk, got into an accident, totalled his car but it was not her fault. So far she hasn't been charged and the other person was.
