Road Rules in El Salvador

In Mexico I met a few people who had driven down from the US and they all had stories of being hitten up by the cops for a bribe for minor transgressions, so when we came a cropper with the fuzz in El Salvador, the experience was a little surprising. After a night of emptying a few bottles of rum from the in pool bar, in classic '80s movie style, a little worse for wear all four of us packed in to the Tamboleo Azul (The Blue Wobble - a VW camper van that a Kiwi guy had driven down from California) with boards piled on top and headed Nicaragua way. About an hour in we came to a junction, and confused without a map we stopped and asked a local for directions, he pointed us straight ahead. A couple of hundred metres down the road we realised we should have turned, so on a two lane one way highway we do a u-turn and drive against the flow of traffic. The first car we said heading towards us is, yep you guessed it, a cop car. They signalled to pull over and then stopped just in front of us, turning the car off, and wandering over the see what we were up to. Bevan, the Kiwi driver, in is best broken Spanish, responded to their demands for the papers for the cars, and then simply said we wanted to go to the border, we missed the turn-off and so we were going back. There was a very pregnant pause, the cops looked at each other, and then admonished him for driving the wrong way on a one way street.
That seemed to be the length of it, as they then proceeded to explain how to get to the border, and then gave us an escort, lights flashing and all, driving the wrong way back to the turn off, and then a further couple of kilometres to a petrol station at the next turnoff.
Moral of the story - if you want to drive the wrong way up one way streets, do it in El Salvador.
As Bevan replied to a gringo we met at the border who inquired about driving difficulties in Central America, I prefer it here, because the only rule is, if you can get away with it, do it - it is far more intuitive driving !!
