Insights
Top tether use for child car seats remains low, below 50%, even with safety campaigns. Education on proper installation, especially in older vehicles, is crucial for child passenger safety.
Area of Science:
- Pediatric Safety
- Traffic Safety Research
- Child Passenger Restraint Systems
Background:
- Top tethers enhance child restraint system safety in vehicles.
- Despite known benefits, top tether utilization by parents is notably low.
- This study addresses the persistent issue of underutilization of a key child safety feature.
Purpose of the Study:
- To determine the current prevalence of top tether use in forward-facing child restraints.
- To update estimates on the adoption of this safety measure among caregivers.
- To identify factors influencing top tether usage.
Main Methods:
- An observational survey was conducted in the Washington DC metropolitan area.
- Data were collected on 1543 forward-facing child restraints in various vehicle types.
- Certified technicians recorded tether usage and installation details for parked vehicles.
Main Results:
- Top tethers were used in 43.0% of observed forward-facing child restraints.
- Tether use varied by vehicle type, being lowest in pickup trucks (17.2%).
- Usage was slightly higher in newer vehicles (2001 and newer) at 47.5%.
Conclusions:
- Observed top tether use remains below 50%, indicating a need for improved safety practices.
- Lower usage in older vehicles highlights a risk, as many children still use them.
- Further education on tether importance and retrofitting options is recommended for enhanced child passenger safety.
Background:
Use of top tethers with forward-facing child restraints is a simple way for parents to keep their children safer when travelling in passenger vehicles, but tether use remains low.
Objectives:
To obtain an updated estimate of top tether use.
Methods:
Data on forward-facing child restraints were collected through an observational survey in the Washington DC metropolitan area during July-August 2010. The study sample included all forward-facing restraints that were installed in parked passenger vehicles and visible such that tether use could be observed. For each restraint, certified child passenger safety technicians collected information on the vehicle, seat row, restraint position, and tether.
Results:
A total of 1321 cars, minivans, pickups, and sport utility vehicles, with a total of 1543 forward-facing child restraints, were observed. Tethers were used with 43.0% of all forward-facing child restraints. Tether use was similar (42.7-45.4%) among cars, minivans, and sport utility vehicles but lower (17.2%) for pickups. Tether use was higher (47.5%) for 2001 and newer vehicles, but dropped to 43.0% when only taut installations were considered.
Conclusions:
Despite LATCH education campaigns and the increased availability of tether anchors, observed tether use was less than 50%. Tether use was even lower in older vehicles, yet many children continue to travel in these vehicles. If tether anchors are unavailable, parents should be encouraged to retrofit vehicle seating positions. Because many child restraints are still installed with vehicle seat belts, efforts to educate parents on the importance of tether use regardless of installation method may be warranted.

Consider two children sitting on a seesaw, which has negligible mass. The first child has a mass (m1) of 26 kg and sits at point A, which is 1.6 meters (r1) from the pivot point B; the second child has a mass (m2) of 32 kg and sits at point C. How far from the pivot point B should the second child sit (r2) to balance the seesaw?
