I did not make myself very clear that I was talking about my driving experience in the SW and SE of the UK. I can not imagine that any tests will keep the poorly lit trucks off the road her in the DR .. Driving at night is perilous but at least all the horses and cattle on the highways and autopistas seem to just a bad memory.While bad driver behaviour is very important and is the largest contributing factor to accidents here in the DR, highway patrol here is very limited, so it's hard to do much about it. Vehicle inspections won't change that either.
Many of the other safety items are important, too. Several times I've been behind trucks that had to stop fairly quickly, but w/o functioning brake lights, I came uncomfortably close to rear ending him. Same with motos at night with no tail lights and headlights. I've come close to hitting a couple of them.I
