While there are several mandatory requirements in the driver's daily log book, the one most likely to cause trouble with the Department of Transportation is the driver's hours of service. According to About.com, minor math mistakes can sometimes cause a driver to receive a ticket. Tickets for hours of service violations range from $1,000 to $10,000 per occurrence.
According to the Department of Transportation, service regulations and the driver log book are means of ensuring driver safety. The DOT implemented new requirements for hours of service for all commercial drivers in July 2013. The regulations limit the number of hours and regulate the times when the driver operates a commercial vehicle.
If the driver is involved in an accident or his truck breaks down, the law requires the driver to document the incident in the log book. It requires the driver to include the time, city and state where the problem occurs.
Mistakes in addresses, a lack of shipping documents, errors with addresses and leaving out the beginning or ending city are common reasons for the return of logs to drivers. The increasing use of electronic logs reduces the number of illegible log books returned to drivers for correction.
