It doesn't take a stormy night to cause a big truck accident. It may be surprising to hear that as many as 71% of big truck accidents occur on dry roads and in good weather, and 75% take place during the day. What, then, is the primary cause of big truck accidents? Big truck drivers are four-and-a-half times more likely to be involved in accidents caused by drowsiness. Even though there are strict laws governing the amount of continuous hours a commercial truck driver can drive, some still squeeze more driving hours in. If you are involved in a big truck accident, you should contact a truck accident lawyer to help you discover the cause and pursue a claim. They can request the "black box" and learn how long the driver actually was on the road before the accident and help you file a claim for the accident.
