The first laws on using a mobile while driving were introduced back in 2003.
But every year dozens of drivers in Essex get behind the wheel and use a mobile device.
It is illegal to hold a phone or sat nav while driving a car or riding a motorcycle.
The law still applies if you are at traffic lights, queuing in traffic or supervising a learner driver.
You can use a hand-held phone while safely parked or if you need to call 999 in an emergency and it is unsafe to stop.
Those who end up in court are given six penalty points and fines of about £200.
Here are cases heard in the last three months involving Essex drivers.
