buses not staying on road

[gadolinite]

 :afro:On the island of norgova, I am running bus routes, I got everything right except one thing.  While the bus crosses the bridge, in the middle somewhere, it runs off the road and bumbs the car divider, then gets back on track.  After it crosses the bridge, it does not want to stay on the road at all.  The route prior to the bridge is A OK, everything after is messed up.  What is the matter?  I am getting the bus to move with move waypoints.  

 :)thank you for your time and energy, assistant x

If you're using the move command instead of waypoints, use object id's for locations...specifically, use road section id #'s. Also, make sure the bus driver's behaviour is set to careless. Here's a copy of one of my bus scripts. Just stick a bus with driver on the road in the town of Loukov. Give it a name and execute this script using the busname-
example: [bus1] exec "busline1.sqs"

;Bus line 1 starts in Loukov moving South
