Tires<br />
For good traction, vehicle tires should have a minimum <strong>of</strong> 2/32 inch <strong>of</strong><br />
tread. It is against the law to drive a vehicle on any tire that has body ply or<br />
belt material exposed or any tire that shows tread or sidewall separation.<br />
Exhaust System<br />
A vehicle must have an exhaust system that is in good working order<br />
and in constant operation. It must meet noise and emission standards set<br />
by the <strong>Department</strong> <strong>of</strong> Environmental Quality (DEQ). Your vehicle must<br />
not be driven if it causes more noise than is reasonably needed for good<br />
operation. If your vehicle produces too many pollutants, you are breaking<br />
the law. If your vehicle is located in the Portland or Medford area you will<br />
need to pass a DEQ inspection.<br />
Windows and Windshield<br />
You should keep the windshield and other windows clean (both inside<br />
and outside) so you have good visibility. Bright sun or headlights on dirty<br />
windows make it harder to see. If you smoke in the vehicle, a fi lm will build<br />
up on the windows, so you need to clean the inside <strong>of</strong> the windows frequently.<br />
No sign, poster, one-way glass, adhesive fi lm, or glaze application is<br />
allowed on the windshield, the windows forward <strong>of</strong> or on either side <strong>of</strong><br />
the driver’s seat, or the rear window, if the material prohibits or impairs<br />
the ability to see into or out <strong>of</strong> the vehicle.<br />
Remember: Most <strong>of</strong> what you do in driving is a reaction to what you<br />
see, so you should be sure you have a clear view out <strong>of</strong> the vehicle.<br />
Windshield Wipers<br />
Good working wipers are required. They are important to driving safely.<br />
Rearview Mirror<br />
The driver must be able to see at least 200 feet behind the vehicle at<br />
all times, and with all loads, on a straight, level road. If a trailer or load<br />
obstructs the rear view, then outside rearview mirrors on each side <strong>of</strong> the<br />
motor vehicle are required. These mirrors need to be extended beyond the<br />
width <strong>of</strong> the trailer or load so the driver can see 200 feet behind the vehicle.<br />
Horns and Sirens<br />
A vehicle must have a working horn you can hear from 200 feet away.<br />
Sirens or similar devices may be used only on authorized emergency vehicles.<br />
Fenders and Mudguards<br />
Most motor vehicles and trailers must have adequate fenders or mudguards<br />
behind all wheels. The exact requirements vary with the type <strong>of</strong> vehicle.<br />
