Trans-Supply Blog – Road & Airport Safety At It's Best

1. The first thing to know: what speed limit will my rumble strips need to be approved for?  We have strips that are only designed for up to 35 mph, and we have others designed for 40 mph+.  If you put a slow speed strip on  a fast road such as a highway, you will end up with a mess on your hands.
2. Some states may require your strips are DOT approved, approval varies state to state.
3. The slower speed strips take (3) 46″ long sections to a make up one long strip (11′ lane).  Usually it’s 3 long strips in each lane in each direction, meaning you would need 3x3x2 (the x2 is for each way) or 18 strips total to cover 1 lane in each direction.  That is our most common order size.
4. The faster strip we sell is one 11′ section, so our most common order would be 6 strips covering one 11′ lane in each direction.

1. Figure out the size you need.  When talking size we are almost always talking about the size of the display itself, although the trailer size can be important if you don’t have much space on the street.  Display sizes available: 3′ x 6′, 4′ x 8′, 6′ x 10.5′, & 6′ x 11.5′.
2. Do you need it to display images?  We aren’t talking full color landscape photos, just simple road safety type images like a worker symbol or a flagger symbol.  If you do need this, it’s called ‘Full Matrix’
3. How long does it last without sun?  All our units are designed to be able to go 21 days without the sun.
4. Popular add ons that typically cost extra: modem option gives you the ability to change the message remotely over the internet without going up to the board & radar option so you can display a car’s speed as it goes by.

It’s important to try and not get lost in the details because it can get as technical as buying a car with these units.  Focus on what you need, read through the spec sheets provided, and more often than not these will come ‘out of the box’ with everything you would require and more.
