As a supplement to *qwertxyz*'s answer, which gives the correct scansion, I'll note that this line fits into the scheme described in D.S. Raven, *Latin metre* §66:

> The 'weak' third foot caesura is far less common in Latin than in Greek ... [I]n the most developed type of hexameter verse ... it is nearly always combined with 'strong' caesura in the fourth foot *at least* ... and usually also with 'strong' caesura in the second foot...

The relevant parts of the example provided (*Aeneid* 1.87) correspond closely to your line (except that the second foot is spondaic instead of dactylic):

insequitur | clamorque | virum | stridorque rudentum
