On unixes, traceroute typically uses UDP by default (nowadays, ICMP is often an option, as are TCP SYN packets). Windows' tracert uses ICMP.

I believe this is because you need root privileges/special capabilities to send ICMP packets.

Yes. I wasn’t perfectly clear there. You’re correct for the initial src packet, the TTL exceeded response is ICMP, I think always.
