When it comes to drunk driving charges, there are many things to consider. In fact, some people may be surprised to find out that the legal limit for drunk driving is lower than they expected for certain drivers, such as those who have not reached the legal drinking age. In Jacksonville, Florida, DUI charges can completely upend a person's life. For example, they may be sentenced to prison for an extended period of time, face harsh financial penalties or lose their job. To make matters worse, their record could return to haunt them years later, when they are applying for a job.
