There is a lot of traffic here in puerto Rico especially around 8am, 12pm and 4pm. So we try to avoid driving around those times of day. And pack on the patience! If you are the first car at the light you will get the horn as soon as it turns green :-) so don't take it personal and ignore. When driving be aware of not only cars but horse riders and mopeds. I get a little stressed out when I drive so thankfully gab drives most of the time.
