SHULMAN, Judge.
Defendant was indicted for the offenses of driving under the influence, reckless driving and speeding. Defendant appeals, pro se, the judgment of the trial court entered in accordance with a jury verdict of guilty on all counts. We affirm.
As appellant has failed to present argument or authorities in support of his contentions of error, such contentions are deemed abandoned. Terrell v. State, 138 Ga. App. 74 (5) ( 225 S.E.2d 470).
We have nonetheless reviewed the judgment on the general grounds. As there was sufficient evidence to authorize the verdict of guilty (on all counts), we must affirm the judgment of the court below. Ridley v. State, 236 Ga. 147 (1) ( 223 S.E.2d 131).
Judgment affirmed. Deen, C. J., and McMurray, P. J., concur.
