Limitations and Warnings

Trinity Highway, in compliance with the NCHRP Report 350 “Recommended Procedures for the Safety Performance of Highway Safety Features”, contracts with FHWA approved testing facilities to perform crash tests, evaluation of tests, and submittal of results to the FHWA for review.

The MPS 350® X system was tested to meet the impact criteria, requirements, and guidelines of NCHRP Report 350. These tests, specifically set forth by FHWA, evaluate product performance by utilizing established impacts outlined by NCHRP Report 350 involving a range of vehicles on the roadways, from lightweight cars (approx. 820kg [1800 lb.]) to full size pickup trucks (approx. 2000 kg [4400 lb.]) as specified by the appropriate highway agency. A product can be certified for multiple Test Levels. The MPS 350® X system is certified to the Test Level(s) as shown below:

Test Level 3: 100 km/h [62 mph]

These FHWA directed tests are not intended to represent the performance of systems when impacted by every vehicle type or every impact condition existing on the roadway. This system is tested only to the test matrix criteria of NCHRP Report 350 as approved by FHWA.

Additionally, the MPS 350® X system was tested to meet the impact criteria, requirements, and guidelines of TD 49. These tests, specifically set forth by The Highways Agency, evaluate product performance by simulating those impacts outlined by TD 49 involving a typical range of vehicles on our roadways, from lightweight cars (approx. 900 kg [2000 lbs.]) to heavier cars (approx. 1500 kg [3300 lbs.]) as specified by The Highways Agency. A product can be certified for various speed levels as shown below:

TL3.UK: 110 km/h [68 mph]

Highways Agency directed tests are not intended to represent the performance of systems when impacted by every vehicle type or every impact condition existing on the roadway. This system is tested only to the test matrix criteria of TD 49 as approved by the Highways Agency.

Trinity Highway expressly disclaims any warranty or liability for injury or damage to persons or property resulting from any impact, collision or harmful contact with products, other vehicles, or nearby hazards or objects by any vehicle, object or person, whether or not the products were assembled in consultation with Trinity Highway or by third parties.

The MPS 350® X system is intended to be assembled, delineated, and maintained within specific state and federal guidelines. It is important for the highway authority specifying the use of a highway product to select the most appropriate product configuration for its site specifications. The customer should be careful to properly select, assemble, and maintain the product. Careful evaluation of the site lay out, vehicle population type; speed, traffic direction, and visibility are some of the elements that require evaluation in the selection of a highway product.

After an impact occurs, the debris from the impact should be removed from the area immediately and the product should be evaluated and restored to its original specified condition or replaced as soon as possible. All components and assemblies should be inspected and any parts that are damaged should be replaced with original Trinity Highway replacement parts. Contact the Customer Service Department prior to repair if you have any questions (see p. 3).

Controlling Skid Distance (Roll Ahead)

The use of a TMA on the back of a truck will not:

Affect the skid (roll ahead) distance of an impacted truck. KEEP WORK CREWS CLEAR!

Controlling skid distance (roll ahead):

Skid distance is significantly increased and is less predictable for lightweight shadow vehicles.

Skid distance is reduced and is more consistent when heavier shadow vehicles are used.
