 More than two-thirds of the respondents were obese; 69.6% had a BMI > 30 kg/m<sup>2</sup>, and 47.6% had a BMI > 33 kg/m<sup>2</sup>. 35.6% of CMVDs surveyed had a BMI > 35 kg/m<sup>2</sup>. Figure 1 presents a frequency histogram of BMIs of the respondents. Obesity correlated with snoring loudness (the louder the snoring, the greater likelihood of obesity) (p<0.05) and with hypertension (p<0.05). More than a third (39.5%) of participants reported hypertension, which correlated with feeling tired/fatigued after sleep (p<0.05)
+=== 4.3. Sleepy Driving ===
+With regard to drowsy driving, 20.5% answered positively to the Berlin Questionnaire query about falling asleep while driving. Correlates of sleepy driving are reported in Table 2. Sleepy driving was not associated with BMI, hypertension (p=0.07) or gender, but strongly correlated with severity and frequency of snoring and with witnessed apneas.
+=== 4.4. Witnessed Apneas ===
+Twenty-one percent of the commercial motor vehicle drivers endorsed the symptom of witnessed apneas; correlates of this symptom are also presented in Table 2. Witnessed apneas were not correlated with BMI, gender, or hypertension, but correlated with classic OSA symptoms.
