Is it legal to drive with a broken tailight if only the plastic is but light works fine?

The legality of driving with a broken taillight varies by jurisdiction and it's important to confirm the specific regulations for your area. Generally, if the plastic cover of the taillight is broken but the light itself is still functional, it may not be considered illegal in some jurisdictions.

However, it's important to note that the light must be fully operational and visible from a specified distance to ensure the safety of other road users. Some countries may have specific regulations regarding the condition and functionality of vehicle lighting, including taillights.

To ensure compliance, it's always advisable to promptly repair or replace a damaged taillight to avoid any potential legal issues or safety concerns.
