The case of State v. Clark, 446 So.2d 293 (La. 1984), not cited in the state's memorandum, held that "substantial compliance" with R.S. 32:661 will support a conviction. Other cases have reached a similar result, such as State v. Sims, 426 So.2d 148 (La. 1983); Dabney v. Dept. of Public Safety, 298 So.2d 295 (La.App. 1st Cir. 1974), writ denied 302 So.2d 25 (La. 1974); Kolb v. State Dept. of Public Safety, 299 So.2d 877 (La.App. 4th Cir. 1974). We do not agree that there was "substantial compliance" with R.S. 32:661 in the present case.
