The Complete Guide for Immigrants and Americans Life in the USA is a complete guide to American life for immigrants and Americans. All rights reserved. On limited access roads, which include the national interstate highway system, you must enter and exit the road only at specified interchanges. Often but not always these will be toll roads, run by the states. You will pay tolls at toll barriers.
Tolls are also common at bridges and tunnels.
Many large roads and bridges now have electronic toll collection lanes which require a special device to be affixed to your car. Make sure to avoid these lanes if you don't have the device. On some toll roads, you will be given a toll ticket when you enter the system. The amount of the toll you will pay will depend on which exit you use. Be careful not to lose the ticket, otherwise you may be charged the highest possible toll.
