seatbelts are not required in the older vans true as in the case of our van we had ,and yes you can carry a child in the back wether its safe or not . but you cannot carry a child by law under the age of three if you do not have full belts ie lap and diag ones fitted ,not even lap belts on rear facing seats are acceptable as a child seat needs lap and diag belts , that is the only reason i had to part with our van, two babies under 3 ( grandsons may i add i havent been on the viagra) i checked with the police and other authorities so even if a newer van has lap belts you still canot carry an under three
