While the economy is greatly helped by the commercial trucks that run along the highways of Oklahoma and other states, it is well known that when you get into an accident with one of them, your car is likely totaled and you are probably injured. The drivers of big rigs are well aware of the fact that they need to be careful to drive safely; however, complacency creeps in and all of a sudden you are hit and they are liable.
Semi-trucks have "no zones" that make you invisible to the truck driver. These are to the left and right of the truck and immediately in front and behind. A good rule of thumb is that, if you can't see the mirror on the truck, the driver cannot see you either.
If you are trying to pass a truck, you need to be extra careful and go slowly. Maneuvering to the right of a truck that is turning right is another area that you need to be careful in. Have you noticed that when a truck makes a turn it isn't clear what they are doing unless they remembered to hit their blinker? They tend to bow out to give room to the curve they are making.
Many times, trucks don't give themselves enough stopping room. They need about 500 feet to come to a full stop if they are going 55 mph. Cutting in front of them is not a good idea unless you leave a large space so that they can react.
If a commercial truck is changing lanes, you need to be aware that they may hit you. Often, truck accidents occur because the trucker is not seeing the cars beside him. This isn't your fault, but you can be on guard against it in the future.
Your best bet is to always drive carefully around semi-trucks. Sometimes, it doesn't even matter that you were careful. You are hit and hurt. Knowing your next steps can be vital at a time like this.
