Can I drive with emission problem?
The short answer is that it is generally not recommended to drive with an emission problem. Emission issues can lead to increased air pollution, reduced fuel efficiency, and potential legal consequences. However, the specific circumstances and severity of the emission problem can impact whether it is safe or advisable to continue driving.
Understanding Emission Problems
Emission problems refer to issues with a vehicle's exhaust system that cause it to release excessive amounts of pollutants into the air. This can be caused by a variety of factors, such as faulty catalytic converters, malfunctioning sensors, or problems with the engine or fuel system. Driving with an emission problem can have several negative consequences:
- Environmental impact: Increased emissions contribute to air pollution, which can be harmful to both the environment and public health.
- Legal issues: Many regions have strict regulations on vehicle emissions, and driving with an emission problem may result in fines or other legal penalties.
- Fuel efficiency: Emission problems can reduce a vehicle's fuel efficiency, leading to higher fuel costs and increased environmental impact.
- Mechanical issues: Unresolved emission problems can also lead to further damage to the vehicle's engine or exhaust system, resulting in more costly repairs.
It's important to note that the severity of the emission problem can vary, and in some cases, it may be possible to continue driving with a minor issue while taking steps to address the problem.
Factors to Consider
When deciding whether to drive with an emission problem, there are several factors to consider:
- Severity of the problem: If the emission problem is relatively minor, such as a small leak or a sensor issue, it may be possible to continue driving while making plans to have the problem addressed. However, if the problem is more severe, such as a malfunctioning catalytic converter, it is generally advisable to avoid driving until the issue is resolved.
- Legal requirements: Check your local laws and regulations regarding vehicle emissions. In some areas, driving with an emission problem may be illegal, and you could face fines or other penalties.
- Proximity to a repair shop: If you are close to a repair shop or service center, it may be possible to drive a short distance to have the problem addressed. However, if you are far from a repair facility, it may be better to have the vehicle towed to avoid further damage or legal issues.
- Potential for further damage: Continuing to drive with an emission problem can sometimes lead to additional damage to the vehicle's engine or exhaust system. Assess the risk of this before deciding to drive.
In general, it is best to address emission problems as soon as possible to minimize the environmental impact, legal risks, and potential for further mechanical issues. If you must drive with an emission problem, do so cautiously and with a plan to have the issue resolved as soon as possible.
Can I drive with an emissions fault?
It's not recommended to drive with the Check Emission System warning light on until you know the cause. Long-lasting damage and extensive repairs can result. How often should I have my emission system checked? Other than your routine maintenance, there's no need to check the emission system unless the light comes on.
Can I still drive my car if it says emissions system problem?
You can likely still drive your car if the emissions system light is steady, but it is not recommended, and you should schedule a diagnostic check as soon as possible to avoid potential engine damage or reduced fuel efficiency. If the light is flashing, it indicates a severe issue like a engine misfire, and you should avoid driving the car and have it towed to a mechanic immediately.
What to do for a steady emissions light
- Avoid long drives: Limit your driving to only what is necessary until you have the issue diagnosed.
- Drive cautiously: Avoid aggressive driving, high speeds, and heavy loads like towing.
- Check the gas cap: A loose gas cap is a common and simple fix. Ensure it is tightened and the light may turn off after a few driving cycles.
- Monitor performance: Pay attention to any changes in how your car is running, such as unusual noises, a lack of power, or a decrease in fuel efficiency.
- Schedule a check: Get your vehicle to a professional for a diagnostic check as soon as you can.
What to do for a flashing emissions light
- Pull over safely: Find a safe place to pull over immediately.
- Do not continue driving: Avoid driving the vehicle further to prevent significant and expensive damage, especially to the catalytic converter.
- Arrange for a tow: Have the vehicle towed to a mechanic or dealership for inspection and repair.
How long can you drive with an emission light on?
It is safe to drive your car for 50 to 100 miles. If there is an issue with the sensor, turning the check light off takes some time. But if it is a serious issue behind the checked light, it will probably start blinking.
How much to fix emission problems?
The cost to fix emission problems ranges from a few dollars for a new gas cap to over a thousand dollars for a major component like a catalytic converter, with common repairs like replacing an oxygen sensor costing around $100-$250. The final price depends on the specific part that needs to be repaired or replaced.

What you should do
- Check the gas cap first: A loose or damaged gas cap is a very common and inexpensive cause of a "check engine" or "check emission system" light. Tightening it is free; replacing it costs around $5-$28.
- Get a diagnostic test: Since the warning light can be triggered by many different issues, a professional diagnostic scan is the best way to determine the exact problem.
- Consider the long-term cost: Ignoring a minor issue, like a bad oxygen sensor, can lead to more expensive problems, such as a failing catalytic converter.
- Consult the Bureau of Automotive Repair: In some areas, a program like California's STAR program can help with repair costs.
- Don't ignore the light: A warning light indicates a problem that could cause damage to your vehicle over time.
