Never Buckle Two Children with One Safety Belt
Taking those laws into consideration, buckling two children into a seat belt may be not only unsafe but illegal as well. Even if the children in question are old enough to be buckled in to an adult seat belt, the safety issues with having two children secured by one belt are potentially catastrophic.
Depending on the ages of the children and the availability of adult supervision, making two trips where all children can be properly and safely restrained is preferable to doubling up. Finding another adult who can drive some of the children is another responsible way to address having more kids than seat belts.
