Can someone explain to me why traceroute uses UDP datagrams for probes?

The firewall in my router doesn't seem to allow these packets back in once they leave.

I would like to be able to run traceroute as a user instead of root (since running as root is the only way to use ICMP echo instead of UDP).

Any info would be greatly appreciated.

TIA.
