I support a high speed standard such as recommendations from MUARC in Australia would present, at least 40 mph (64 km/h) for majority of fatal crashes. We demand at a minimum compliance with Vision Zero which your current recommendations violate thru lack of any effort to save lives as first priority. Guards must be energy absorbing (Energy absorption: 50kJ minimum) for future car designs and must be low to the road 16 inches (406 mm) for future car designs. Angled struts must be attached to strengthen ends of guard for offset impacts and must be required to upgrade older guards. If these minimums are not met and the standard only legalizes guards “already on the road” then we demand an end to this rulemaking, immediate withdrawal.
When we crash test guards at 30 to 35 mph (48 to 56 km/h) we get guards for 50 years that perform at 30 to 35 mph (48 to 56 km/h). When you try something over and over and over again and get a negative result, why would you continue this activity. If we crash test guards at high speeds perhaps we will see guards that perform at high speeds. The FHWA tests crash attenuators in 62.2 mph (100 km/h) crash tests (Real World Crash Speeds) and attenuators protect cars and trucks in crashes at 62.2 mph (100 km/h) and more!

RECOMMENDATIONS I support from MUARC
1. Barrier test Forces:
P1 (outer edge) P2 (off centre) P3 (centre)
200 kN 200 kN 100 kN
2. Barrier height: 400mm
3. Barrier width: Within 100mm of the outer frame of the rear of the truck
4. Energy absorption: 50kJ minimum
That should do it for quick comment!
