It’s worth noting that every state has their own driving laws although it’s fair to say that they don’t differ greatly. State-specific driving laws can be found here. Generally speaking the maximum speed limit most states is 65mph (110km per hour) except where signs indicate slower speeds.
If you’ve never driven in the US before then driving Route 66 is going to be a real treat! Aside from the fantastic scenery you’ll also most likely be driving a rental car which will almost certainly mean automatic transmission. At first I was unsure of how I’d find driving an automatic car but I very quickly came to love the ease and comfort. Stop. Go. Simple. If you’ve never driven an automatic before it’s best to tuck the left foot away in a comfortable position and operate the brake/gas pedals with the right foot only. This will help avoid any sudden braking should you have the urge to go for the clutch!
Driving on the right-hand side of the road, in the left seat, takes a little adjustment and you may find yourself reaching for the window every time you want to change gear! However, as you’ll most likely be driving an automatic this is rare. Auxiliary controls (indicators, wipers, etc…) will also be reversed but the pedals remain in the same position (minus the clutch in an automatic - this is replaced by an oversized brake pedal).
In the States, STOP means stop! You should always come to a complete stop at a STOP sign even if the road appears deserted. This may seem strange to foreign drivers at first, as every car in a queue of traffic will do the same, but it’s a well-enforced law and shouldn’t be overlooked.
In most US states, and all of the those on Route 66, it is legal to turn right at a red light. Always look left to ensure the path is clear and don’t be bullied into turning if you feel uncomfortable. However, in cases where it is considered dangerous to turn right there will be signs stating “Do not turn right on red”.
Here is a website I found very useful before my first driving experience in the US. It gives detailed information on traffic lights and intersections (junctions).
