The 6-hour course is extremely comprehensive and covers all aspects of defensive driving in considerable depth. The 1-hour course covers the main subjects but in less detail than the 6-Hour course If you are unsure which course to take, you should contact your agent to see if they require our 6-hour course or if they will accept the 1-hour course. If you have already registered for the 1-hour course but require the 6-hour course, we would be more than happy to switch your course registration to the 6-hour course at no additional cost.
