Vehicle noise, emissions, spills and littering

The Road Code distinguishes emissions, spills, throwing objects and excessive noise. The relevant evidence can range from technical measurements to direct observation.

What to check in your case

For noise or emissions, check any measured threshold and device. For a spill, identify the source and time of the fault. For a thrown object, establish which seat it came from.
