Ignition Interlock Devices

Oklahoma Ignition Interlock Information from Ward Lee & Coats.

An ignition interlock is an electronic device that is installed in your car to prevent someone from starting and operating the car who has alcohol in their system.

We have worked with different interlock companies over the years and currently recommend that all of our clients use Smart Start. We do not currently recommend any other companies. If for some reason you do not follow our advice then there are other companies out there who produce these devices, but you have to make certain that you pick one that is approved by the Oklahoma Board of Tests. The approved list can be found on BOT’s website – CLICK HERE to go to their website.

Currently they offer a unit for $65.99 a month and free installation. Their contact information is below.
