Final answer:
A solid line on your side of the center dash stripe means you must not pass other vehicles and stay in your lane. It's a safety regulation to prevent accidents in areas where passing is dangerous.
Step-by-step explanation:
When a solid line is on your side of the center dash stripe on the road, it typically means that you are not allowed to pass other vehicles in that area. The solid line indicates that it is not safe to pass, due to potential hazards such as oncoming traffic, limited visibility, or road conditions. It is a traffic regulation that ensures the safety of all road users. Instead, you must stay in your lane and follow the road at a safe speed until the road markings indicate that it's safe to pass or change lanes.
