Traffic signs are the oldest and most commonly used Traffic Control Device (TCD). These signs convey messages in words or symbols and erected to regulate, warn, or guide the road users (motorists, and pedestrians). This study investigated the level of compliance of traffic control devices among drivers with different sociodemographic characteristics in Ilorin. A descriptive research design of survey type was used in the conduct of the study. The population for this study covers commercial and private drivers in Ilorin. The research instrument used for the study is a well-structured questionnaire. The data gathered were analysed using frequency counts and percentage for the demographic data, and factors that affect the non-understanding of drivers to traffic control devices. Statistical analysis was done with SPSS. For chi- square, only the years of driving experience was found statistically significant with a p-value of 0.006 and for Analysis of Variance (ANOVA) both educational experience and years of driving experience were found to be statistically significant with p-value of 0.001 and 0.000. It was deduced that major factors affecting the non-understanding of traffic control devices by drivers in Ilorin were lack of previous knowledge of the signs, lack of adequate enforcement and non-availability of control devices on most roads in Ilorin.

The effectiveness of traffic signs, which are used often to promote safe driving and are designed to convey critical information quickly, is contingent on drivers' ability to understand them. Therefore, researchers in Ilorin set out to determine how well-understood and compliant traffic control devices were among drivers representing a range of demographics. The study was conducted using a descriptive survey research approach. The population for this study covers commercial and private drivers in Ilorin. The three local government areas in Ilorin were selected Ilorin South, East and West. A multi-stage sampling technique was used to select three hundred and eighty-four (384) drivers from the population for the study. The research instrument used for the study is a well-structured questionnaire. Statistics including frequency counts and percentages were used to examine the demographic information, the total proportion of drivers who properly recognized the traffic control device, and the variables that contribute to drivers' inability to comprehend traffic control devices. The average comprehension percentage of warning signs, regulatory signs, information sign, driver’s knowledge of road marking 56.1%, 60.3%, 64.6% and 59% respectively. The study's findings revealed that 60% of drivers in Ilorin generally comprehended traffic control devices.
