Chicago's dooring law strictly prohibits opening a vehicle door on the side facing moving traffic unless it is entirely safe to do so and will not interfere with the flow of other vehicles. Furthermore, the law forbids leaving a door open on the traffic side for any extended period.
Understanding Chicago's Dooring Law
Often referred to as the "Dooring Ordinance," this crucial regulation in Chicago aims to prevent collisions between vehicle occupants opening doors and passing traffic, particularly bicyclists. The core of the law emphasizes safety and non-interference with movement.
The specific provisions can be summarized as follows:
| Prohibited Action | Conditions for Prohibition |
|---|---|
| Opening a vehicle door on the side available to moving traffic | Unless and until it is reasonably safe to do so, AND can be done without interfering with the movement of other traffic. |
| Leaving a vehicle door open on the side of a vehicle available to moving traffic | For a period of time that is considered excessive or unsafe. |
This ordinance is codified in the Chicago Municipal Code, Section 9-40-160, titled "Opening and closing vehicle doors."
Key Components of the Law
The language of the dooring law highlights several critical aspects:
- Reasonably Safe: This implies a duty of care on the part of the person opening the door. Before unlatching, one must actively check for oncoming traffic, including bicycles and motorcycles, to ensure no immediate danger.
- Without Interfering with Traffic: Even if no direct collision occurs, opening a door that forces other vehicles to swerve or brake suddenly is a violation. The door must not impede the natural flow of traffic.
- Duration of Open Door: The law also addresses leaving a door open for an extended period. This is crucial because even a safely opened door can become a hazard if left open longer than necessary, especially in busy urban environments.
Why the Law Matters: Preventing Dooring Accidents
Dooring accidents occur when a vehicle door is opened into the path of another road user, most commonly a cyclist or motorcyclist. These incidents can lead to severe injuries, including broken bones, head trauma, and even fatalities, as riders can be thrown into traffic lanes. Chicago's law serves as a vital preventive measure to protect vulnerable road users and maintain traffic safety.
Practical Tips for Avoiding Dooring
Adhering to Chicago's dooring law is not just about avoiding a ticket; it's about ensuring safety for everyone on the road. Here are practical ways to prevent dooring accidents:
- The "Dutch Reach": This technique involves opening the car door with your far hand (e.g., use your right hand to open the driver's side door). This naturally forces your body to swivel, prompting you to look over your shoulder and into your side mirror, giving you a better view of approaching cyclists or traffic.
- Check Mirrors and Blind Spots: Always check your side mirror and physically turn to look over your shoulder before opening your door, even if you think the street is clear.
- Educate Passengers: Ensure that anyone riding with you, especially children, understands the importance of checking for traffic before opening their door.
- Park Safely: When possible, park further from bike lanes or busy traffic to allow more buffer space for opening doors.
Who Does the Dooring Law Apply To?
The Chicago dooring law applies to:
- Drivers: They are responsible for ensuring the safe opening of their own door.
- Passengers: Passengers are equally responsible for opening their doors safely and are subject to the same regulations.
