Controlled Access Roads
Controlled access roads are roads that have limited entrances. This method of limiting access to a road helps the traffic flow on that road. The best example of this type of road is a freeway. Think about it, every street that crosses or meets the freeway is not able to directly get on the freeway. To enter the freeway these cars drive down a road that is parallel to the freeway and then an entrance is available. Roads that are parallel to the freeway are often called service roads, access roads or frontage roads. These roads face two situations where yielding is required. The most obvious one is when vehicles exit the freeway onto the service road. When this happens cars on the service road must yield. If you are trying to enter the freeway from a service road you must yield to the cars on the freeway. This requirement to yield when entering the freeway means coordinating the time you enter the freeway with other cars on the freeway, and is absolutely critical for success in this effort. Just remember the controlled access road has the right of way.
