As noted earlier, WC19-compliant wheelchairs provide four easily accessible attachment points that greatly facilitate effective wheelchair securement using a four-point, strap-type tiedown.Because these wheelchairs have been successfully crash tested, transportation personnel can have confidence that the wheelchair will support the student and be effectively secured if the vehicle is involved in a crash or rollover.
Although components from different manufacturers may look similar, they may not engage effectively.

In some cases, it may be necessary to thread the ends of the lap belt through openings in or between wheelchair components.
If these items cannot be removed and stored, add-on items should be attached to the wheelchair by tiedown straps, and dense padding should be placed between hard trays and the student in the wheelchair.
Consideration should also be given to replacing hard trays with support surfaces made from dense foam during transportation.
