Intelligent speed assistance, or ISA, is a new anti-speeding technology that will be used on every vehicle sold in the European Union. The EU regulation (part of the larger General Vehicle Safety Regulation) takes effect today, and it states that all new models and types of vehicles brought to the European market must have an ISA system. The policy does not apply to any current vehicles on display — at least not yet. Every new car sold in the EU must have an anti-speeding device by July 2024.
