Dear Mr. Heald: 

This letter is in response to your May 14, 2020 request for the Federal Highway Administration 

(FHWA) to review a roadside safety device, hardware, or system for eligibility for reimbursement 

under the Federal-aid highway program. This FHWA letter of eligibility is assigned FHWA 

control number WZ-417 and is valid until a subsequent letter is issued by FHWA that expressly 

references this device. 

Decision 

The following device is eligible within the length-of-need, with details provided in the form 

which is attached as an integral part of this letter: 

• Shur-Curb Traffic Separator 

Scope of this Letter 

To be found eligible for Federal-aid funding, new roadside safety devices should meet the crash 

test and evaluation criteria contained in the American Association of State Highway and 

Transportation Officials’(AASHTO) Manual for Assessing Safety Hardware (MASH). 

However, the FHWA, the Department of Transportation, and the United States Government do 

not regulate the manufacture of roadside safety devices. Eligibility for reimbursement under the 

Federal-aid highway program does not establish approval, certification or endorsement of the 

device for any particular purpose or use. 

This letter is not a determination by the FHWA, the Department of Transportation, or the United 

States Government that a vehicle crash involving the device will result in any particular 

outcome, nor is it a guarantee of the in-service performance of this device. Proper 

manufacturing, installation, and maintenance are required in order for this device to function as 

tested. 

This finding of eligibility is limited to the crashworthiness of the system and does not cover other 

structural features, nor conformity with the Manual on Uniform Traffic Control Devices.

Evaluation 

Results 

3-90 (ll00C} 

Test 3-90 involved an llO0C vehicle 

impacting the Shur-Tite Shur-Curb Traffic 

Separator at a target impact speed of 62 mi/h 

and target impact angles between 0° and 25°. 

The target CIAs for the tests were selected to 

maximize the risk of vehicle rollover and/or 

excessive vehicle deceleration. The tests 

were performed at target CIAs of 25°, 15° 

(cross V), and 0° (tire on curb). In addition, 

the llO0C vehicle was tested while 

performing a lane change maneuver. 

The results of the tests conducted on March 

17, 2020 are found in TTI Test Report No. 

690900-STPl-8 dated April 2020. 

The Shur-Curb Traffic Separator yielded to 

the llO0C vehicle in all four test 

configurations, allowing controlled 

penetration of the vehicle. No detached 

elements, fragments, or other debris was 

present to penetrate or show potential for 

penetrating the occupant compartment, or tc 

present undue hazard to others in the area. 

No occupant compartment deformation or 

intrusion was observed. The ll00C vehicle 

remained upright during and after the 

collision event in all test configurations. The 

llO0C test vehicle was directed into the 

installations by a live driver, and were 

performed without the instrumentation 

necessary for determining occupant risk. The 

vehicle remained stable as it traversed 

through the channelizer installations and did 

not demonstrate excessive decelerations. 

The fact that a live driver was used during 

testing and no injuries were reported indicatE 

the occupant risk is within MASH limits. 

The Shur-Curb Traffic Separator performed 

acceptably during all test configurations for 

MASH Test 3-90 for longitudinal channelizers. 

PASS 
3-91 (2270P) 

Test 3-91 involved an 2270P vehicle 

impacting the Shur-Tite Shur-Curb Traffic 

Separator at a target impact speed of 62 mi/h 

and target impact angles between 0° and 25°. 

The target CIAs for the tests were selected to 

maximize the risk of vehicle rollover and/or 

excessive vehicle deceleration. The tests 

were performed at target CIAs of 25° 1 15° 

(cross V), and 0° (tire on curb). In addition, 

the 2270P vehicle was tested while 

performing a lane change maneuver. 

The results of the tests conducted on March 

17, 2020 are found in TTI Test Report No. 

690900-STPl-8 dated April 2020. 

The Shur-Curb Traffic Separator yielded to 

the 2270P vehicle in all four test 

configurations, allowing controlled 

penetration of the vehicle. No detached 

elements, fragments, or other debris was 

present to penetrate or show potential for 

penetrating the occupant compartment, or tc 

present undue hazard to others in the area . 

No occupant compartment c;:feformation or 

intrusion was observed. The 2270P vehicle 

remained upright during and after the 

collision event in all test configurations. The 

2270P test vehicle was directed into the 

installations by a live driver, and were 

performed without the instrumentation 

necessary for determining occupant risk. The 

vehicle remained stable as it traversed 

through the channelizer installations and did

The fact that a live driver was used during 

testing and no injuries were reported indicate 

the occupant risk is within MASH limits.
