DEF Fluid laws in Virginia
The use and sale of diesel emissions reduction fluid (DEF) are generally permitted for vehicles requiring it for emissions control. There are no specific state-level restrictions on its purchase, possession, or transport for typical consumer use. It is considered a standard automotive product. This applies to both commercial and private vehicles that are equipped with selective catalytic reduction (SCR) systems. While largely unregulated from a legal prohibition standpoint, it's essential for consumers to ensure they are using DEF that meets industry standards for quality and performance, as using improper or contaminated fluid can negatively impact vehicle emissions systems.
