Hold-back Speed Bump / Hold-back Speed Bump

Hold-back Speed Bump

With economy booming, more families and cooperates can afford vehicles, but with the bright side coming, it also
brings up the bad side. Although dangerously enough, more and more drivers accidentally or deliberately choose
to drive in wrong direction when not seeing vehicles coming. Road kill and injure tend to go up when doing so. We
decided that, while advocating and advertising about basic traffic laws and regulations, it is necessary and extremely
urgent to design and manufacture a Hold-back Speed Bump. It is easy-sighted, customer-friendly and extremely
convenient to install, maintain and disassemble.
