What Is a Divided Highway?
A divided highway is a road with a barrier or median in the middle. This keeps cars going different ways apart. The 連邦高速道路局 says these roads have special entry and exit spots. Drivers can only get on or off at certain places. This stops cars from crossing into the other side. Most divided highways have more than one lane each way. This helps cars move better and lowers the chance of head-on crashes.

Compliance and Regulations
MUTCD規格
The 均一な交通制御装置のマニュアル, またはMUTCD, makes the rules for road signs in the U.S. These rules help keep signs simple and easy to read. The MUTCD says how big a divided highway sign should be and what colors to use. Signs need to be large so drivers can see them from far away. The colors must stand out, with yellow backgrounds and black symbols. Where the sign goes is important too. Signs should be placed before the road changes, so drivers have time to react. The MUTCD also says signs must be easy to see during the day and at night. Signs use reflective materials so drivers can see them in the dark or when it rains.
Traffic workers check if each sign follows these rules. They look at how high the sign is, how far it is from the road, and the angle it faces. サインがルールに従わない場合, they fix it or put up a new one. These steps make sure all drivers get the same warning, 彼らがどこにいても.
Local Adaptations
States and cities sometimes need to change the rules for their own roads. They may have heavy traffic, special lanes, または悪天候. Local groups can add their own rules if they still follow the main MUTCD rules. Here are some ways local areas change divided highway signs:
- Preferential lanes might let some cars enter all the time or only at certain places.
- Managed lanes can switch uses, like becoming HOV lanes during busy times.
- Changeable message signs can show travel times or warn about traffic in managed lanes.
Some states have their own MUTCD books. These must still match the national rules, but they can make exceptions if state law or studies say it is okay. Local groups must follow state rules, which usually match federal rules, unless a federal aid project is happening.
| 側面 | 説明 |
|---|---|
| State MUTCDs | States can have their own MUTCDs or extra rules, but they must match the national MUTCD. |
| Substantial Conformance | State MUTCDs must follow the national MUTCD, but some exceptions are allowed if state law or studies support them. |
