You can lawfully allow an object to extend beyond the left side of your vehicle?

Yes, you can lawfully allow an object to extend beyond the left side of your vehicle, but it must adhere to specific regulations. Generally, the object should not extend more than a certain distance, often around 3 inches, and must be properly marked or flagged if it exceeds that limit. Additionally, it’s important to ensure that the extension does not obstruct the driver's view or pose a hazard to other road users. Always check local laws and regulations, as they can vary by jurisdiction.
