You are in your car towing a trailer on a road with oncoming traffic and want to turn left. What must you particularly remember when you set off again?

When towing a trailer and turning left on a road with oncoming traffic, it is especially important to remember both the increased length of your vehicle-trailer combination and the fact that your acceleration is reduced. The longer vehicle requires more space to clear the intersection safely, and slower acceleration means you need a larger gap in oncoming traffic to pull away without causing danger. However, flashing your lights to warn oncoming traffic is not allowed and could cause confusion. In summary, always allow for extra space and time when maneuvering with a trailer, and never rely on actions like flashing your lights to communicate with other drivers. This approach helps you stay safe and avoid mistakes on similar questions in the future.
