How can I tell if a stroller trike meets safety standards?

Yes stroller trikes need to comply as well, all of the trikes with SmarTrike have been certified but you can also check for yourself by running a few simple checks (especially if buying second hand); check the brakes, harness, stability, locking devices, steering, backrest and weight limit. The easiest way to tell is to look for the label that contains the identification of the UK manufacturer and the number and date of the British standard.
