Review on Triangle Aluminum Reflective Vehicle Engineering Safety Products for Occupational Health and Safety Signs & Signals by Sean Spence

I cycle to work with my dogs in the bike trailer and now the days are shorter, I get home after sunset. That distinguishes me from the cars that approach from behind. The street I'm on has two lanes in each direction and a center turn lane with multiple ramps. The speed limit is 35 mph and I'm going about 10 mph. But less than a quarter mile up the road the speed is 45 mph and most cars are accelerating so I felt I needed a big slow moving vehicle sign to identify oncoming traffic to warn drivers. So far, so good.
