|
|
Follow another vehicle.
|
|
|
Cross an intersection.
|
|
|
Turn at stop signs.

Explanation
Always maintain a safe distance between your vehicle and the one ahead of you. If the pavement is dry, maintaining a 4-second following distance allows you to safely steer or brake to avoid a hazard. If you are following too closely and the vehicle in front abruptly stops or slows down, you won't have enough time to prevent a collision.
