One very basic thing: driving in the US is rather simple and most likely not a challenge to any average German driver. Anyhow, I describe a few differences you need to consider:
Automatic
Most cars in the US have automatic transmission. That means there is no clutch pedal. It’s best to not use your left leg at all and only accelerate with your right leg. If you use both legs, you might accidentally operate both pedals at the same time (that means accelerate and brake at the same time). Moreover, you could accidentally make a (too) hard stop simply by pushing the brake as much as you would push the clutch. Because of that: put your left leg aside, and only use the right leg.
The automatic transmission has a parking mode. Sometimes, it’s only possible to shift to driving mode when you stand on the brake pedal. If you don’t use the break, the parking mode is locked and cannot be removed.
US Cars are huge ships
Cars in the US are remarkably taller than anything we have in Germany. They have jeeps (real jeeps not SUVs). Also, many family vans are everywhere. There are also some extremely grand vehicles (RVs) that make half a house. We had a Dodge Grand Caravan once, it was a very good car but we were worried about its size and how to park and turn it. Turns out, not a problem at all. The car was only average size in the US. We did fit into every parking space; in general we found enough space to turn, park and drive.
Parking: Valet Parking and Handicapped Parking
You need to get used to valet parking. Germans don’t like to give their car to anyone else. That is totally different in the US, valet parking is everywhere.
Handicapped Parking is available everywhere. That is the same in Germany but in Germany people tend to leave these parking spots empty and not use them at all, even if they are elidible. Some handicapped people even choose to not use them at all. In the US that is very different: veterans have special number plates and always use handicapped parking.
General Speed Limit and Driving on the Interstate
There is a general speed limit on the interstate: 80 miles. This is mandatory and most people only drive 80. Every now and then, a single car or some motorbikes take over but that is not very common. It’s not like Germany where the speed limit seems to be the minimum speed.
Because of this, most cars simply drive right next to each other on the interstate. The rule to drive right is not as strict as it is in Germany. There can be someone on your right lane for several kilometer right next to you or someone else is taking over on the right. In general American drivers tend to drive cozily right next to each other.
You can easily stay on the middle lane for a longer period of time. Americans take the right or left lane to take over and don’t bother at all. That makes life in a new city much easier: you can always choose the middle lane if you don’t know where to go next.
Driving is very relaxed
Everyone is far more relaxed than German driver. You don’t run into other shouting, aggressive drivers if you make a minor mistake like driving too slowly, changing your lane a bit clumsily or using the wrong dipper.
There are some cities and routes in the US that have a reputation of being particularly difficult because of aggressive driving, e.g. Ocean Drive to Key West or Miami. We do not have any negative experience, driving in these areas was maybe a bit less relaxed than anywhere else but definitely still ok and not a problem at all.
Stop Signs, Traffic Lights and Crossroads
Americans like Stop Signs. In Germany, we have a stop for one driver, the one that has to stop. (usually the one coming from a secondary road). In the US, all four drivers have a stop sign. That also means all of them have to stop. Figuring out who is supposed to go first is always a bit difficult. Allegedly, on “first come first serve” principle. But that is difficult. If you are not so sure, just wait and let the others go first. Stop signs are very common, you find many of them everywhere. Always be careful with stop signs.
Signs and traffic lights are on the opposite side of the crossroad. Always look at the opposite side to see them.
Many Lanes and Flyovers
A very typical thing is a road with many lanes. In cities up to 8 or more lanes. Don’t get freaked out by that, you can always stay in the middle lane if you are unsure.
A second thing is flyovers. Many roads are elevated and run on bridges and several levels, in particular on big crossroads. These flyovers are in every city. The GPS tends to be misleading in these cases: going straight can mean going straight on the upper level (on the bridge) or the lower level (under the bridge). If you get this wrong, it might take a while to find the next exit.
How It Is to Have a Police Officer Pull You Over
Yes, we had a police officer pull us over. Our driver missed a stop sign and totally blew it. Bad for us: the police officer was standing right at that junction. He followed us with his lights on. You have to stop at the next secure place. We were in a town and could stop right away.
The police officer stopped right behind us and came walking along the sidewalk. I read somewhere that you are not allowed to open your bag, look for something in your handbag or in general open any bag or anything else in particular the glove box and keep your hands visible all the time. We opened the window and and left the hand on the steering wheel or in front of our body.
The officer asked a couple of questions, where we are from, if we are on vacation and where we are going. He also said, he assumes we know what a stop sign is and that we have stop signs in Germany too. We confirmed that answered all his questions friendly and after a few minutes he let us go. I have to say we were very lucky!
I have to say, I think we made one mistake. There were four of us in the car but we only opened the front row windows. I think we should have had opened all the windows to show all the cars passengers to the police officer.
He asked who was in the car. We answered but it was not visible for him because the back windows were dark.
Toll In Florida
Florida has several toll stations, mostly for bridges. There are regular toll stations where you pay in cash, stations for credit card users and on the very left a “Fast Lane” with no paying station at all. You can just pass with only little less speed on these lanes. For that, you need a “Toll Pass”, they film this pass while you pass through the station and your toll is charged on your credit card.
At first, we did not know but rental cars come in general with this “Fast Lane Pass”. Like this, we could always take the fast lane and never had to wait. The charging on the credit card was correct after that holiday.
