PC §9.51. ARREST AND SEARCH
(d) A person other than a peace officer acting in a peace officer's presence and at his direction is justified in using deadly force against another when and to the degree the person reasonably believes the deadly force is immediately necessary to make a lawful arrest, or to prevent escape after a lawful arrest, if the use of force would have been justified under Subsection (b) and:
(1) the actor reasonably believes the felony or offense against the public peace for which arrest is authorized included the use or attempted use of deadly force; or
(2) the actor reasonably believes there is a substantial risk that the person to be arrested will cause death or serious bodily injury to another if the arrest is delayed

If he was driving drunk one could make an argument that the requiremnet in para 2 was met.
