When traceroute times out on intermediate hops, how is it able to continue on to the destination as follows?

[root@localhost network-scripts]# traceroute -I  www.google.com
traceroute to www.google.com (216.58.196.228), 30 hops max, 60 byte packets

Answering my own question here.

The servers in the middle can reject ICMP requests, but will still pass along packets to the next server once the TTL is incremented for subsequent transmissions.
