Many of the smaller towns in Mexico don't have stop signs or red lights. But guaranteed they have topes! Usually the smaller towns have one at the entrance to the town, and another as you leave the town.
There are many different types of topes. But, they are the number one road hazard in Mexico! Some topes have signs warning that there is a tope ahead. Some topes are painted white or yellow. Some are not, and some have the paint worn off. Sometimes, there is a sign warning of a tope, but then there is no tope! Of course this makes you slow down anyhow.
Once, we hit a tope without seeing it first. Sometimes, if the tope is in the shade, it is very difficult to know it's there. We are ALWAYS on tope watch when we are driving in Mexico. If Ruth sees a tope, she will warn me about it even if she knows I have seen it. All she needs to do is to say "tope" and I know to slow down because there have been times where I haven't seen one, and there's been times where I've seen one and she hasn't. Four eyes are better than two when it comes to topes!
Many topes in a row!
Once, a couple of years ago, we hit a large tope without slowing down. Unbelievable, but neither one of us saw it! The front end went over it hard, but without incident. But I'm sure the back end of Sherman left the ground! Our bedroom TV came crashing down, and all the clothes in Ruths closet broke away from the hangar brackets. We were so surprised there wasn't more damage.
Topes do a better job of slowing people down than stop signs, yield signs, speed limits, or red lights. You really have no choice but to slow down. Like I said, they are VERY effective.
