The same is true for vehicles registered in West Texas. If you live in Midland, there is no emissions testing. Should they be allowed to drive that car in Dallas or Houston where emissions testing is required?
But in post 72 you claimed they do have their cars inspected ---there's no reason to claim they do because it's not true.
"According to data from the Juarez General Police, there are 360,000 cars operating in the City and an estimated 60% of these cars are 1985 models or older. Furthermore, the ITESM calculates that only about 15 to 20% of the cars in Juarez meet proper emission standards while the rest have either never been checked or aren't checked enough to indicate whether an engine tune up is required."
