Kevin Johnston (“Driver”) appeals a judgment entered in the Circuit Court of St. Louis County (“trial court”) denying the reinstatement of his driving privileges. The trial court found that the Director of Revenue (“the Director”) properly suspended Driver’s license based on his con*466viction in Kentucky for driving under the influence. We affirm.
I. BACKGROUND
The facts of this case are not in dispute. Driver resided in Kentucky until 2005, when he moved to the state of Missouri. Upon moving to Missouri in 2005, Driver surrendered his Kentucky license for a valid Missouri license.
On April 23, 1996, long before Driver moved to Missouri, the state of Kentucky charged him with Operating a Motor Vehicle Under the Influence of an Intoxicating Beverage — 1st Offense (“DWI”). On July 15, 1996, Driver was found guilty of that offense and sentenced. He filed a notice of appeal on July 23, 1996. The appeal remained pending for 3,458 days, and the conviction was not affirmed until January 10, 2006. The record provides no explanation for the nearly nine and one half years’ pendency of the Kentucky appeal.1
After Driver’s case was affirmed on appeal, the Kentucky Department of Transportation notified the state of Missouri of Driver’s DWI conviction. Kentucky’s notice lists the citation date as April 23,1996, and the conviction date as January 10, 2006. The Director of Revenue (“the Director”) sent Driver a notice on February 21, 2006 stating that his driving privileges would be suspended for thirty days, pursuant to section 302.304 RSMo 20002, effective March 22, 2006.
Driver then filed a Petition for Review in the trial court on March 21, 2006, pursuant to section 302.311. The trial court denied his Petition and held that “points were properly assessed by the Department of Revenue for a Kentucky Driving While Intoxicated.” Driver appeals.
II. DISCUSSION
We will affirm the trial court’s decision unless it is unsupported by substantial evidence, it is against the weight of the evidence, it erroneously declares the law, or it erroneously applies the law. Jennings v. Dir. of Revenue, 986 S.W.2d 513, 513-14 (Mo.App. E.D.1999) (citing Murphy v. Carron, 536 S.W.2d 30, 32 (Mo. banc 1976)). However, “[i]f the evidence is un-controverted or admitted so that the real issue is a legal one as to the legal effect of the evidence, then there is no need to defer to the trial court’s judgment.” Friedrich v. Dir. of Revenue, 124 S.W.3d 30, 32 (Mo.App. W.D.2004) (quoting Hinnah v. Dir. of Revenue, 77 S.W.3d 616, 620 (Mo. banc 2002)).
In his first point on appeal, Driver argues that the trial court erred in affirming the Director’s suspension of his driving privileges because the Director exceeded her authority in issuing the suspension. We disagree.
Driver’s argument stems from his assertion that he was convicted of DWI on July 15, 1996, rather than January 10, 2006. Under the provisions of the Driver License Compact (“the Compact”), section 302.600, Driver argues that Kentucky, not Missouri, was his home state at the time of his conviction. Therefore, Driver asserts, the Director exceeded her authority when she suspended his license based on a conviction that occurred when Missouri was not even his home state.
We believe, however, that this case may be resolved independent of the Compact because Missouri’s statutory scheme authorizes the Director to suspend Driver’s license for a valid Kentucky conviction. “[T]he [Director is authorized to rely on *467convictions in other states to suspend driving privileges.... ” West v. Dir. of Revenue, 184 S.W.3d 578, 580 (Mo.App. S.D.2006) (quoting Carlson v. Fischer, 149 S.W.3d 603, 606 (Mo.App. W.D.2004)); see also section 302.160. Section 302.160 provides that, when the Director receives notice of a conviction in another state, “which, if committed in this state, would result in the assessment of points, the director is authorized to assess the points and suspend or revoke the operating privilege when the accumulated points so require as provided in section 302.304.” In Missouri, a first-time DWI offense assesses an eight-point penalty. Section 302.302.1(10). The Director must suspend the license and driving privileges of any driver who accumulates eight points in eighteen months.3 Section 302.304.3. Thus, the Director validly suspended Driver’s license when she received notice from the Kentucky Department of Transportation of Driver’s DWI conviction on January 10, 2006.
Driver’s argument that he was actually convicted on July 15, 1996, is of no avail. The Kentucky Department of Transportation’s notice to the Director lists Driver’s date of conviction as January 10, 2006. Thus, the state of Kentucky designated January 10, 2006, as the conviction date. Driver’s argument, in a Missouri court, that the Kentucky court’s judgment erroneously determined his date of conviction amounts to a collateral attack. See BLACK’S LAW DICTIONARY 255 (7th Ed.1999) (defining “collateral attack” as “[a]n attack on a judgment entered in a different proceeding”).
In Carlson v. Fischer, 149 S.W.3d 603 (Mo.App. W.D.2004), Mr. Carlson attempted to challenge the propriety of an Ohio court judgment that found him guilty of driving under the influence. 149 S.W.3d at 607. He presented evidence to a Missouri trial court that, in Ohio, he had never failed to appear, was never told his bond was being forfeited, never entered a guilty plea, and was never found guilty of operating a motor vehicle while intoxicated. Id. The Western District stated that Mr. Carlson could not challenge the Ohio court judgment in a proceeding under section 302.311 (outlining the procedures for appealing the Director’s suspension or revocation of a license). Id. The Court went on to say: “[a] driver cannot collaterally attack previous convictions in an action to challenge a driver’s license being revoked or suspended.” Id. (quoting Kayser v. Dir. of Revenue, 22 S.W.3d 240, 243 (Mo.App. E.D.2000)). Rather, the Court said that any challenge to Mr. Carlson’s Ohio conviction had to be made in Ohio. Id. at
608. Driver, like Mr. Carlson, improperly attempts to challenge the propriety of a Kentucky judgment — namely, Kentucky’s designated date of conviction — in a Missouri court.
For the foregoing reasons, the Director properly suspended Driver’s license pursuant to section 302.304 for Driver’s January 10, 2006, DWI conviction in Kentucky. Point one is denied.
In his second point on appeal, Driver argues that that trial court erred in affirming his suspension because Kentucky was not a member of the Compact at the time of his conviction, and therefore it remains inapplicable. Having decided Driver’s appeal independent of the Compact, we need not address his second point.
The judgment is affirmed.

. Driver actually accumulated ten points in eighteen months because he was also assessed two points for a conviction for failure to yield right of way in St. Louis County on November 1, 2005. This conviction is not at issue on appeal.
