1) 2 Tolls between Vic Falls and Byo 2) Normal passenger vehicle US$1 per toll 3) Yes there are reports of Cops looking for reasons to fine and bribe you. Best and only approach is make sure they have nothing to fine you for. Have the correct car documents and your drivers licence. Make sure car is not faulty. Then stand your ground and do not be intimdated, ask to go to the police station if necessary, this will soon have them back tracking. Most of the cops are very nice and you will not have any problems. If they are making up ridiculous fines do not accept and ask to go to police station. Never lose your temper and never mention anything political. You will not be stopped at the tolls by police it's at the road blocks they they will check your papers. It sounds worse than it is.
