New Test for Gas Use in Cars
Introduction
Police in southern England are testing a new machine. This machine finds a gas called nitrous oxide in drivers.
Main Body
Two police groups are doing this test. Many young drivers use this gas. It is dangerous. It makes drivers feel dizzy and slow. Some people die in car accidents because of this gas. In the past, police had no fast way to find the gas. They used videos or stories from people. Now, they have a small machine from a company called Respira Technologies. It finds the gas in a few minutes. Police want to see if the machine works well on the road. If it works, all police in the UK will use it. This will make the roads safer for everyone.
Conclusion
The test is new. Police want to see if they can use the machine to stop drivers who use this gas.
